AMD Ryzen 5000 “Cezanne” mobile CPU architecture gets new details

More details about the upcoming AMD Ryzen 5000 mobile processors have surfaced through a leaked presentation. Besides describing the improvements coming with the new architecture, this presentation also includes comparisons between the Ryzen 5000H APUs and the currently available mobile APUs and CPUs from AMD and Intel.

Besides the leaked slides shared by VideoCardz, the website also confirmed that Cezanne APUs will feature a 180mm² die with 10.78B transistors. Compared to the Renoir APUs, that's an increase of 15% and 10%, respectively.

Starting with the performance uplifts over the previous generation flagship SKUs, the Ryzen 9 5980HX comes with a +23% improvement over the Ryzen 9 4900H on single-thread performance. Comparing the Ryzen 9 5900HX to Intel Core i9-10980HK, it delivers up to 19% more single-thread performance than Intel's flagship mobile processor.

These increases result from multiple improvements over the previous generation, including doubling the L3 cache to 16MB and unifying it, employing Zen3 cores, introducing support for LPDDR4 memory, and upgrading die to a monolithic design to reduce latency. All these resulted in an increase in the operating frequencies and IPC.

The CPU part wasn't the only one to be improved. Although the Ryzen 5000 APUs will still use a Vega iGPU, the operating clocks have increased by 350MHz, up to 2.1GHz, resulting in a 10% improvement over the Ryzen 4000 mobile APUs.

Lastly, there are some changes in the power delivery system. Besides featuring per core on-chip power regulation to optimise efficiency, AMD also introduced a deep power state for memory, which further reduces the power consumed. According to AMD, this should result in up to 2 hours of extra battery life.

Laptops equipped with Ryzen 5000 APUs are expected to release in February 2021.

KitGuru says: How will AMD Ryzen 5000 mobile processors fare against the competition? Are you considering buying a new laptop this year? Will you choose one powered by an Intel CPU or an AMD CPU?

DLSS 5 NVIDIA

KitGuru Games: DLSS 5 misses the point

It would be hard to argue that NVIDIA’s DLSS technologies haven’t been a net positive to the PC space, with the machine-learning based upscaler successfully translating lower resolution inputs into a final image which is perceivably sharper while hogging fewer resources. Though somewhat more contentious, the next evolution of DLSS came in the form of Frame Generation, using ML in order to generate additional frames for high-refresh rate gaming. Both techniques can have their issues, but generally speaking they’ve allowed for more people to experience higher-end titles at increased frame rates. DLSS 5, however, takes a sharp pivot, with a very different end goal in mind than the performance-boosting versions that came before.
