A new implementation of ray tracing has appeared on the market, available on a fairly wide range of video cards, including far from the newest ones.
Ray tracing support has been added to the MESA (OpenGL and Vulkan implementation for Linux) graphics library for older AMD GPUs. The list includes adapters with RDNA architecture, Vega models and the highly popular Polaris. Perhaps this is not the whole list. As a result, at least the specified lines of AMD video cards will receive support for ray tracing in the Vulkan APU with the RADV Radeon Vulkan driver.
At the same time, older AMD adapters do not have dedicated blocks to accelerate ray tracing, which means that the performance situation may not be very good. The quality of optimization of the RADV driver for old adapters aggravates the situation.
As a result, some have already been able to try out the new features on the Navi 10 and Polaris 10 GPUs in the Quake 2 RTX game and encountered errors. But recompilation helped.
500 fps in Overwatch 2 at 1440p and Ultra settings. Only the GeForce RTX 4090 can do this.
A few hours before the release of Overwatch 2, Nvidia published an infographic in which they presented performance data for various current models of their video cards in the game. Of course, all the attention here is on the new GeForce RTX 40 (Ada Lovelace) models.
According to Nvidia official data, the GeForce RTX 4090 is the only model that, at a resolution of 2560 x 1440 pixels and ultra settings, can provide frame rates in excess of 500 fps. The result is, of course, impressive. And it is even more impressive against the background of the GeForce RTX 4080, which is one step lower with 16 GB of memory – this model is capable of only 368 fps under the same conditions. However, both of these models are suitable for 360-Hz monitors.
The performance gaps between the GeForce RTX 4080 12GB, RTX 3080 and RTX 3070 are not that big anymore, but still noticeable.
Nvidia recommends using the GeForce RTX 3080 Ti when playing games at Full HD resolutions above 360Hz, while the GeForce RTX 3060 can be used with Full HD monitors that support 144Hz.
Unique behavior of Ryzen 7000 processors. The notorious patches from the Specter vulnerability improve the performance of new CPUs
Recently, various vulnerabilities in processors have been talked about much less often, and users no longer worry about performance degradation due to patches. As it turns out, Ryzen 7000 processors generally benefit from such patches!
At least this is true for Linux, since it was in this OS that the author tested the Ryzen 9 7950X and Ryzen 5 7600X. It turned out that when working out of the box, the CPUs show better performance than when loading a special version of Linux with a deactivated patch from the Specter V2 vulnerability.
Of course, such results do not appear everywhere, and during normal work they are unlikely to be critical. In particular, in total, according to the results of 190 tests, the difference was only 3%.
40 times faster than Xeon Platinum 8380 and six times faster than Nvidia H100. The world’s first universal processor Tachyum Prodigy will be a real monster
Tachyum has revealed new details about its Prodigy processors, which the company calls the world’s first general-purpose processors.
In particular, the performance (FP64) of the top 128-core Prodigy T16128-AIX is three times greater than that of the latest monstrous Nvidia H100 accelerator! If Nvidia’s solution is talking about 30 TFLOPS after the recent spec update, the Prodigy T16128-AIX offers 90 TFLOPS! Single precision (FP32) performance is also three times better: 180 TFLOPS vs. 60 TFLOPS. Moreover, in some other modes (INT8 and FP8) the processor is six times faster than the new Nvidia.
It can also be noted that a standard server rack with liquid-cooled Prodigy T16128-AIX processors offers a performance (FP64) of 12.9 PFLOPS versus 960 TFLOPS for the same rack with Nvidia H100.
Compared to conventional processors, the Prodigy T16128-AIX is four times faster than the Intel Xeon Platinum 8380 in Specrate 2017 INT Performance tests and 40 times faster in double precision floating point calculations. Also, the novelty is better than Google’s fourth-generation specialized TPU.
Recall that Prodigy processors are universal, that is, capable of conditionally executing any code using a dynamic binary translator, so that they can perform tasks that are typical for both CPUs and GPUs or TPUs.
Tachyum expects that it will receive the first samples of its processors before the end of this year, and mass production will start in the second half of next year.
