2016 has been a slow year for graphics cards and while Nvidia launched their high end GTX1070 and GTX1080 solutions – they are strictly for the gaming audience with deeper pockets. AMD have approached their first 2016 GPU launch differently, opting to release their RX 480 – a mid range card priced at $199.99 firmly targeting the mass enthusiast gaming audience.
The new AMD Radeon RX 480 is built on the FinFET 14nm process. For Polaris, AMD selected Samsung and Global Foundries 14nm FinFET based process technology, the densest foundry process available. FinFET transistors are crucial to reduce power consumption while enabling operating voltages which are 150mV lower than the previous generation.
The AMD RX 480 will be available in two different memory capacities, 4GB and 8GB. We have heard retail prices of $199 for the 4GB card and $239 for the 8GB card with UK prices around £180 and £215 respectively. Pricing is a little higher in the UK, but I guess most of us are getting used to that now.
AMD have pointed out that the reference configuration for the RX480 is 4GB of 7Gbps GDDR5 memory and the 8GB boards will feature 8Gbps GDDR5 memory. AMD told us that partner custom boards will vary from these reference specifications, but they will never drop below 7Gbps memory speeds.
Our AMD Radeon RX480 8GB sample shipped directly from AMD and as such there is no box artwork or accessories. We already have some partner cards in our labs, so we will be following up soon with more reviews.
No backplate on the AMD RX 480 reference card, but perhaps custom models from AMD partners will include one. We can see the PCB length is very small, with the cooler intake actually extending the length of the GPU.
AMD have ditched DVI and VGA completely, which won't be a problem for too many people in 2016. There are three DisplayPort connectors (1.3 HBR/1.4 HDR ready) on the card, alongside an HDMI connector which is 2.0b capable …
… this means if you have a big television set you can game at 60hz at Ultra HD 4k resolution across the HDMI port. Good to see AMD finally rectifying this.
The RX 480 takes power from a single 6 pin power connector, shown above.
The PCB of the RX 480 is very small – the cooler overhangs the PCB with the fan intake visible from the rear of the card. This cooler is very basic indeed – there are no heatpipes, just a simple, small heatsink positioned in the middle of the plastic cooler shroud. We are likely going to see more sophisticated cooling solutions coming from AMD partners in the coming weeks.
The latest version of GPUz gets most of the information from the card, although further details can be seen in the table on the previous page.
AMD have released a new overclocking software suite which they are calling ‘Radeon WattMan'. This software can control GPU voltage, engine clocks, memory clocks, fan speed and temperature.
While we are only reviewing the reference AMD card today, partner cards are likely going to be sold in various states of overclock, so we felt it was important to try and present some findings today with the RX 480 when overclocked. This should, in theory, give us an indication of what will be possible when the 14nm architecture is pushed to the limit.
The software suite also has a histogram which records and displays the GPU activity, clock speeds, temperature and fan speed. This data can be used to tweak settings to try and improve performance in various areas.
As you can see from the image above, the interface could certainly be classed as attractive, although I can't help but feel AMD could have crammed all this into a much smaller, cleaner interface and without the need for transparency on all the panels. I prefer a simple, small, clean interface. There is for instance no need for all the space taken up with 7 states for the memory overclocking, as only one is applicable with the rest basically redundant.
I spent a lot of time overclocking the RX 480 8GB and using how to best set up the parameters in Radeon WattMan. Simply increasing the voltage and clock speeds won't lead to great results and often the card will deliver lower performance than at the default settings. This is directly related to the small heatsink that AMD have inside their cooler shroud. The RX 480 will throttle.
I got best results by increasing the clock speeds in STATE 6 and STATE 7 as these are the states that all games will target under load. I settled on a maximum speed of 1,375mhz for the core at STATE 7 and increased the voltage to 1150. This is the maximum voltage you can set in WattMan for the RX480 sample we received.
It is worth reiterating (if you haven't read the full RX 480 review so far) that the AMD reference cooler on this card has no heatpipes and only a single, small blower style fan to push air.
To help negate throttling I increased the fan speeds to maximum and increased the temperature threshold from 80c to 90c. Under load the fan was painfully loud, but without question partners such as Sapphire will be releasing superior custom cooled solutions in the coming weeks.
Overclocking the memory seemed to cause stability problems on our test bed, with games randomly crashing to the desktop. I therefore decided to leave memory as is, but will try again when we present our next AMD partner card review and I have more time. AMD said they were aware of some overclocking issues and gave me a new driver, but this happened the day before launch so I have been unable to make time to look into this further.
All our game tests in this launch review today will be showing the RX 480 running in two different states. One at the default clock speeds of 1,266mhz and the other with the fan at full and temperature limits at maximum, running at 1,375mhz. This is to try to negate throttling.
I have spent the last couple of weeks benchmarking a selection of AMD and NVIDIA cards with the latest drivers on one of our new 6700k test beds. We are using the AMD Crimson Edition Display Driver, Version 16.15.2211 and Nvidia ForceWare 368.39 driver. The RX480 8GB was tested with the latest 16.6.2 beta driver specifically for the launch. Due to public demand we also add in a range of tests at 1080p to supplement the results at 1440p and Ultra HD 4K resolutions.
We list each resolution test for every game on its own page – meaning if you are just interested in 4K resolutions for instance, you can skip the other resolutions without effort. If you want to read the whole review and find all the page changes annoying – click on our menu system top right of these pages, and head to ’33. view all pages’.

AMD are keen to promote the fact that the RX 480 is a modest cost graphics card, but that it is completely VR ready. At reader request we added this free Steam VR ready test today to this review.
The RX 480 scored 6.6 points in the Fidelity rating test, which is a ‘high' rating. My colleague Jon Martindale recently produced some VR content for KitGuru and we published some results with AMD hardware (HERE) and Nvidia hardware (HERE) which can be used as a comparison. The Nvidia GTX970 Jon tested scored 6.7 points, so performance of the RX 480 8GB is very closely matched indeed. 0 frames (0%) below 90 fps is good to see.
3DMark 11 is designed for testing DirectX 11 hardware running on Windows 7 and Windows Vista.

Dirt Rally is developed by British video game developer Codemasters using the in house Ego engine. Development began with a small team of individuals following the release of their 2012 video game Dirt: Showdown. Codemasters have emphasised a desire to create a simulation with Dirt Rally. They started by prototyping a handling model and creating tracks based on map data. The game employs a different physics model from previous titles, rebuilt from the ground up.
We test at 1080p with 8x MSAA and the ultra image quality setting enabled.
Dirt Rally seems to run a little faster on the GTX970 at 1080p, although when the RX 480 is overclocked the positions swap.

At Ultra HD 4k the results get interesting. The RX480 has been behind the GTX980 at 1080p and at 1440p, but the positions change. When overclocked the RX 480 averages 34 frames per second, around 8 behind the reference GTX980 ti.
Rise of the Tomb Raider is a third-person action-adventure game that features similar gameplay found in 2013's Tomb Raider. Players control Lara Croft through various environments, battling enemies, and completing puzzle platforming sections, while using improvised weapons and gadgets in order to progress through the story. It uses a Direct X 12 capable engine.
We enable Direct X 12, Vsync is off and graphics are set to the ‘very high' profile, shown above. We test the Nvidia Titan Z with the SLi optimisation both disabled, then enabled. This is clearly marked in the graph. See more HERE.
This is a great engine and we can see performance from the RX 480 is quite strong, averaging almost 60 frames per second.

Grand Theft Auto V is an action-adventure game played from either a first-person or third-person view. Players complete missions—linear scenarios with set objectives—to progress through the story. Outside of missions, players may freely roam the open world. Composed of the San Andreas open countryside area and the fictional city of Los Santos, the world is much larger in area than earlier entries in the series. It may be fully explored after the game's beginning without restriction, although story progress unlocks more gameplay content.
We maximise all the image quality settings, but leave anti aliasing turned off, as it dramatically impacts performance.
At 1080p the RX 480 delivers a great gaming experience in Grand Theft Auto 5, ahead of both R9 390 8GB and R9 380X. When overclocked the RX 480 moves a couple of frames ahead of the Palit GTX970.

A tough task obviously for a modest gaming card such as the RX 480. Still we can see performance is slightly ahead of the GTX970 and close to the R9 390.
Just like the original game Metro 2033, Metro: Last Light is played from the perspective of Artyom, the player-character. The story takes place in post-apocalyptic Moscow, mostly inside the metro system, but occasionally missions bring the player above ground. Metro: Last Light takes place one year after the events of Metro 2033, following the canonical ending in which Artyom chose to proceed with the missile strike against the Dark Ones (this happens regardless of your actions in the first game). Redux adds all the DLC and graphical improvements.
Quality-Very High, SSAA-on, Texture Filtering-16x, Motion Blur-Normal, Tessellation-Normal, Advanced Physx-off.

At Ultra HD 4k the RX 480 doesn't really deliver a good gaming experience, but the same can be said for the GTX970 and 380X. Overclocking helps drive 3 more frames per second from the hardware, but it is still not smooth enough to play.
Hitman (2016) is a third-person stealth video game in which players take control of Agent 47, a genetically enhanced, superhuman assassin, travelling to international locations and eliminating contracted targets. As in other games in the Hitman series, players are given a large amount of room for creativity in approaching their assassinations. The game is being released in stages, which hasn't proved too popular with a large audience.
We test with many of the settings maximised, SSAO is disabled however as I found it causes some crashing. I have to say that Hitman is a little unstable at times under the best of situations, but we managed to get it running well enough to benchmark. The built in benchmark is very flaky indeed however, so real world runs had to be used.
A great gaming experience at 1080p, averaging well over 80 frames per second. This is in GTX980 territory, and clearly ahead of the overclocked GTX970.

At Ultra HD 4k the RX 480 outperforms the Asus GTX980 Strix, averaging 41 frames per second. When we overclock the core to 1,375mhz the RX 480 pushes ahead of the Titan Z, averaging 44 frames per second. The Nvidia GTX970 is some distance behind.
We have built a system inside a Lian Li chassis with no case fans and have used a fanless cooler on our CPU. The motherboard is also passively cooled. This gives us a build with almost completely passive cooling and it means we can measure noise of just the graphics card inside the system when we run looped 3dMark tests.
We measure from a distance of around 1 meter from the closed chassis and 4 foot from the ground to mirror a real world situation. Ambient noise in the room measures close to the limits of our sound meter at 28dBa. Why do this? Well this means we can eliminate secondary noise pollution in the test room and concentrate on only the video card. It also brings us slightly closer to industry standards, such as DIN 45635.

We test with the automatic fan profile at the default clock speeds and at 100% when we overclock the RX 480 reference board, to the limit. Fan speeds increase between these two settings from 2,200 rpm under load to a constant 5,100 rpm.
When the RX 480 is set at default clock speeds with the fan profile set to automatic, it is actually relatively quiet, although I could always hear the hum of the small single fan under load. There is a specific, somewhat annoying pitch evident with these blower style fans that AMD have been using for years. I have been mentioning it in my reviews for years, but it falls on deaf ears.
When we overclock the RX 480 to breaking point we pushed the fans to 5,100rpm, the maximum setting. This created noise levels of 47.2dBa which is in all honesty, very painful. I could even hear the fan spinning with headphones on.
We didn't notice any coil whine at all from the card, which is reassuring, although with the fan on 100% we really could hear very little.
The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 21c – a comfortable environment for the majority of people reading this. Idle temperatures were measured after sitting at the desktop for 30 minutes. Load measurements were acquired by playing Rise Of The Tomb Raider for 90 minutes and measuring the peak temperature. We also have included Furmark results, recording maximum temperatures throughout a 10 minute stress test. All fan settings were left on automatic.
The RX 480 held steady at 83c in our stress tests, with the core speed throttling when running Furmark (varying between 900mhz and 1025mhz).
We install the graphics card into the system and measure temperatures on the back of the PCB with our Fluke Visual IR Thermometer/Infrared Thermal Camera. This is a real world running environment playing Rise Of The Tomb Raider for extended periods of time.
The back of the PCB holds close just below 80c under extended load, which is quite hot. There is no backplate on the RX 480 reference board so we are getting a direct reading from the PCB itself.
We measure power consumption from the whole system when idle and when gaming, excluding the monitor.
The RX 480 is very power efficient at reference clock speeds with the voltage running as per AMD's default settings. When we increased the core voltage to the maximum figure in WattMan and overclocked the core to 1,375mhz, the power consumption increased by 40 watts from a system reading of 225 watts to 265 watts. By comparison, the same system with a GTX1080 running at reference clock speeds was consuming only 5 watts more.
The AMD Radeon RX 480 8GB is certainly a very capable graphics card and as our readers have been discussing in the build up to launch today the much touted price point of $199.99 really did seem too good to be true.
While American prices seem very competitive the situation in the United Kingdom isn't quite so positive. We have been told by AMD directly that the reference RX 480 4GB will be priced around £180 and the 8GB version which we reviewed today will be around £215. We can always blame UK 20% VAT for the higher prices, but since the announcement of the UK wanting to opt out of the European Union, the pound sterling has devalued to a 31 year low.
On a more positive note, it is refreshing to see that AMD have managed to deliver performance levels ahead of the R9 380x and GTX 970. When manually overclocked to 1,375mhz we found the RX 480 was slightly faster than the R9 390 and very closely matched against the Asus GTX980 Strix – in some engines a little behind, and in others, a little ahead. It really does all depend on the games you want to play.
Power efficiency of the RX 480 8GB is noteworthy – it topped our graph. When we increased core voltage to achieve the maximum overclock possible the power consumption increased by 40 watts. At this level the system load was only 5 watts lower than when fitted with a reference Nvidia GTX 1080.
All in all I have been immensely impressed with the RX 480 8GB, and even my previous niggle of AMD not adopting an HDMI 2.0 port has been addressed. At long last, 60hz refresh rates at Ultra HD 4k resolutions are now a possibility on an HDMI driven television set.
There is only one real concern with the reference RX 480, and it is unfortunately quite a big one. The reference cooler is quite frankly, rubbish. AMD have basically installed a diminutive heatsink on the core and are pushing cold air over it with a small blower style fan that can spin up to 5,100 rpm.
This means that if you want to reduce the temperatures below 80c under load then you are going to need to increase the fan speeds, effectively breaking away from the quiet default profile. Also if you want to overclock and leave the fan on automatic, the card will throttle heavily. WattMan is an attractive, fully loaded software package, but due to the weak cooling system I found you had to really crank the fan speeds and adjust the temperature threshold to the upper end of the scale (90c) to ensure throttling was kept to a minimum. I really do wish AMD would up their game with their reference cooling solutions on launch day.
At 1,375mhz, the RX 480 8GB delivered stellar performance, but I couldn't live with the 47dBa+ noise levels required when the voltage was cranked to get stability. My only reason for including these overclocked results was to give us an early indication of how AMD partners will likely sell their modified, tweaked cards in the coming weeks. I am looking forward to testing the Polaris architecture with a proper heatpipe style cooler and multiple high grade fans in place from companies such as Sapphire.
The RX 480 earns our Worth Buying Award, I would have scored it higher, but the reference cooling system is very poor, and I advise our readers to wait on custom cooled cards from AMD partners before parting with the cash. I am confident with 2 and 3 fan cooling systems and heatsinks connected to high grade heatpipes that cooling proficiency will reap higher overclocks, minimise throttling and reduce noise emissions under load.

Pros:
- excellent performance levels out of the box.
- decent price points.
- overclocking potential looks high.
- high power efficiency at stock settings.
Cons:
- mediocre cooling system on the reference card.
- throttling issues can occur unless fan levels and temperature targets are increased.
- small blower style fan can get loud.
- no backplate.
Kitguru says: The AMD RX480 8GB is a powerful and capable graphics card which appears to exhibit plenty of overclocking potential. While the reference card has performed well in our analysis, the cooling system is rather feeble and we look forward to testing higher grade partner cards in the coming weeks.
