The post AMD Ryzen 7 5800X CPU Review first appeared on KitGuru.]]>
AMD’s Zen 3 Ryzen 9 chips – the 12-core 5900X and 16-core 5950X – have proven to be winners in their respective market segments. But selling for £520 and £750 respectively, there is need for lower cost options to appeal to the mass market. Is the £420 Ryzen 7 5800X 8-core the option that users were looking for? Or has AMD increased the price versus Zen 2 predecessors by too much?

The AMD Ryzen 7 5800X is an 8-core, 16-thread processor that operates with a 3.8GHz base frequency and 4.7GHz maximum boost with a 105W TDP. MSRP is set at $449 but comes in at £420 in the UK. That’s a $50 MSRP increase in price over the Zen 2 Ryzen 7 3800X/3800XT it replaces.

More challenging, though, is the often £90 availability price increase versus the 105W TDP 8-core Zen 2 chip, or £120-130 extra versus the Ryzen 7 3700X.

AMD’s chosen process node is still TSMC 7nm, but it is the tweaked design logic as applied with the frequency enhanced Ryzen 3000XT chips launched in July 2020. That should help reach and sustain higher boost clocks versus original Zen 2 Ryzen 3000X chips.

Unsurprisingly, the Ryzen 7 5800X uses the same Zen 3 architecture as the Ryzen 9 5900X and Ryzen 9 5950X. For more details on the architecture and the differences of Zen 3 versus Zen 2, check out our main Ryzen 9 5000 series launch reviews HERE and HERE.

Put simply, the Ryzen 7 5800X now uses a single 8-core Zen 3 CCX for its sole core CCD chiplet. You still get the same 12nm IO die as the other Zen 3 and Zen 2 processors. Using a single, fully packed 8-core chiplet means that the Ryzen 7 part gets 32MB of L3 cache to go alongside the 4MB of L2 cache via its core count.

That’s a 32MB reduction in L3 cache from the Ryzen 2 dual-CCD chips and is the same amount as the cheaper single-CCD Ryzen 5 5600X.

Put simply, it looks as if AMD has priced the Ryzen 7 5800X based on the premise that it is ‘stealing’ valuable full 8-core chiplets away from the more expensive Ryzen 9 5950X or Zen 3 EPYC processors. As such, the Ryzen 7 5800X looks to be priced as an upsell to the Ryzen 9 5900X that only costs £90 or 21% more in the UK but offers 50% more cores and 100% more cache.

Pricing the 8-core Zen 3 chip at £420 in the UK also brings Intel Comet Lake competitors into play. AMD will be fighting against the 16-thread Core i7-10700K for the title of ‘the fastest 8-core desktop processor’ but the Ryzen chip will do so with a £50 price disadvantage versus the £370 Core i7.

More importantly, however, is the competition brought about by Intel’s £440 Core i9-10850K, which is basically just a 100MHz slower Core i9-10900K but significantly cheaper. This 10-core, 20-thread Comet Lake chip will have a top-end frequency advantage versus the Ryzen 7 5800X and 25% more cores, but AMD will be fighting with the superior Zen 3 architecture and stronger AM4 platform capabilities.

The fight between the Ryzen 7 5800X and the closely priced Core i9 10-core competitor will be particularly interesting, so let’s jump into the testing.

AMD settles Bulldozer class-action lawsuit for $12.1 million https://www.kitguru.net/components/cpu/matthew-wilson/amd-settles-bulldozer-class-action-lawsuit-for-12-1-million/ https://www.kitguru.net/components/cpu/matthew-wilson/amd-settles-bulldozer-class-action-lawsuit-for-12-1-million/#respond Wed, 28 Aug 2019 08:30:11 +0000 https://www.kitguru.net/?p=423123 The class-action lawsuit against AMD over Bulldozer and the definition of a CPU core has now come to an end.

The post AMD settles Bulldozer class-action lawsuit for $12.1 million first appeared on KitGuru.]]>
Many of you will remember the AMD ‘Bulldozer' class action lawsuit, claiming that the series of FX processors were falsely advertised and overstated the number of cores on the chip. The lawsuit has been going on for around four years now but today, it officially comes to an end, with AMD reaching a settlement agreement.

The class action suit alleged that the eight-core Bulldozer FX CPUs were falsely advertised as having eight cores. This stems from the CPU's design, as while Windows would recognise each Bulldozer module as two separate cores, they shared a single FPU as well as instruction and execution resources.

Fortunately, we won't need a judge to try and rule on what is officially classed as a CPU core anymore. AMD has reached a settlement agreement, which will include a $12.1 million pay out, split roughly into $35 chunks amongst US buyers of eight-core Bulldozer chips.

The settlement comes at a good time, as in January, a judge had ruled that the lawsuit could proceed after rejecting AMD's argument that a “significant majority” of consumers agreed with its definition of a CPU core.

KitGuru Says: I didn't expect that we would still be talking about Bulldozer now in 2019 but here we are. It looks like this case can now be wrapped up, although there will be another update in the future when these class action payouts start going out.

There have been a lot of rumours and leaks surrounding Intel’s 9th generation CPUs, which are said to be launching fairly soon. Will there be an eight-core SKU? Will the i7 have hyperthreading? Will it be a new platform? A leak from ASRock has at least answered some of these questions. We now know that Intel will be launching an eight-core CPU and that the existing entry-level H310 chipset will support them.

An ASRock H310 motherboard box leaked over at Videocardz, showing that new shipments will have a sticker on the box confirming eight-core Intel CPU support. This also confirms that H310 motherboards will support these new eight-core processors, although probably with the help of a BIOS update. You can see the leaked image for yourself below:

It is very baffling to see such low-level boards have support for Intel’s flagship CPUs, but it isn’t a bad thing to at least have the choice. It’ll be a surprise though if anyone was to purchase a brand-new eight-core CPU and pair it with an H310 motherboard.

KitGuru Says: It is great news that current generation motherboards will be supported, as Intel has been heavily criticised in the past for forcing users to new platforms when there wasn’t really any need for it. Has this changed your mind on buying one of the new 9th Generation Intel CPUs?

We've been hearing whispers surrounding Intel's upcoming Coffee Lake S processors and new Z390 chipset for several months. Going by Intel's roadmap, these new CPUs are expected to launch in the second half of this year, and this week, we may have got a peek at the intended flagship, with 8 cores and 16 threads.

We are used to benchmark databases leaking hardware details a little early. This week, the folks over at Videocardz managed to unearth an upcoming Intel Coffee Lake S CPU, which was being tested on 3DMark. The key details are that this particular processor features 8C/16T, whereas the current batch of Coffee Lake processors top out at 6C/12T.

The 3DMark Database listing also showed this CPU running at a clock speed of 2.2GHz, but that will likely change by the time this processor launches. The processor was tested on an Intel CoffeeLake S 82 UDIMM RVP motherboard, which is an engineering board used for in-house tests.

Currently, we don't know if Coffee Lake S will launch under the ‘8th Gen' banner, or if Intel will brand it as a ‘9th Gen' CPU. Still, we should learn more as the year progresses, perhaps with a full announcement at Computex.

KitGuru Says: Intel stuck with quad-core designs for its mainstream processors for a long time, but we finally saw steps in a new direction last year with Coffee Lake. We currently have six-core i7 and i5 processors, with Coffee Lake S, it looks like we'll see things go a step further. Are any of you currently planning a new PC build for this year? Will you be waiting to see what Intel brings to the table with Coffee Lake S?

AMD is set to take on Intel once again this year with the launch of its highly anticipated Zen architecture processors. While Socket AM4 is currently poised to launch for some APUs fairly early this year, Zen CPUs won't be arriving until a bit later, with current sources pointing towards an October launch date.

According to a source supposedly close with AMD, (via wccftech), the first Zen/Summit Ridge processor will be an eight-core offering, with dies already taped out and currently being validated through testing. A release is then apparently scheduled for October.

AMD-x86-Zen-Core-635x357

The report also notes that the future Socket AM4 CPU will have a 95W TDP, putting it in-line with Intel's current high-performance mainstream desktop processors in terms of power consumption.

As always when dealing with unofficial information, it is important to note that plans could change and delays could happen. This is also an anonymous source so do take it with a grain of salt. That said, We have been expecting a late 2016 release and an October date would fit that bracket.

KitGuru Says: AMD is finally gearing up to launch the Zen architecture alongside a new ‘unified' AM4 platform that will support both APUs and new CPUs. Are any of you currently waiting on Zen?
