SAM tests on the RX 6800. AMD tunes more than it reveals

SPECviewperf 2020 and SPECworkstation 3

The Smart Access Memory feature is far from perfect. And although it is a useful technology overall, it also proves to be very unstable. What was true today may not tomorrow, and an in-depth analysis shows all those patches. On the one hand, those that eliminate the biggest problems that no one boasts about, and on the other hand, those that raise average performance in small steps.

SPECviewperf 2020

Test platform benchmark; API OpenGL and DirectX; no extra settings.

PC Cooling Guide: Heating Up Ryzen 9 7950 X in Cinebench

Today, we’ll focus on what happens inside a case when a CPU is under heavy load. We’ll run a Cinebench 2024 rendering on a Ryzen R9 7950X cooled by a Noctua NH-D15 G2 air cooler and see how it affects the temperatures and how all the values change with different settings of the system fans’ performance across their entire operating speed range.

AMD CPUs with Zen 6 architecture will still use the AM5 socket

The AMD AM4 platform has a reputation for longevity. For most, it goes back to 2017 an the first Ryzen, but it’s even been used with Excavator APUs in 2016. It supports CPUs and APUs all the way up to the 2020/2021 Ryzen 5000, meaning that three Zen architecture generations of Zen can be used, which has keept older motherboards relevant way longer than is usual. It looks like AM5 platform owners will be similarly lucky. Read more “AMD CPUs with Zen 6 architecture will still use the AM5 socket” »

AMD plans Threadrippers with 3D V-Cache, X3D APUs coming too

AMD has launched the Ryzen 7 9800X3D with second-generation 3D V-Cache technology with a large cache in an extra chipset, which makes it a good (currently the best) CPU for gaming. But this technology is now likely to be deployed more widely. It’s apparently coming to high-performance Threadripper processors for the first time, and could even appear in APUs, i.e. mobile processors for laptops, perhaps as Infinity Cache for their GPUs.
