Prices for Ryzen 9 5900X are falling, Ryzen 7 5800X3D really only pays off for games

The Ryzen 7 5800X3D V-Cache demonstrates how performance can be affected if processor cores reach a 96MB block of data with multiple faster accesses with multiple lower latencies. I testify to this (which has been known since Broadwell with its 128MB eDRAM) and some applications as well.

Developer Sebastian Aaltonen believes that the significant increase in performance for some game titles is due to the fact that these are mainly games optimized to support high FPS, which have a data set adapted to fit a substantial part of the processor’s cache (and frame by frame). the data did not have to load from slower and higher latency RAM). In the case of 96MB capacity, in many games this dataset will fit in the cache as a whole, which results in a significant increase in performance. You will find more in Aaltonen’s contribution.

Extreme performance gains can also be found in some types of workloads in Linux, as the phoronix website test showed. Such extremes can be useful for users who intensively use a particular application or type of load in which similar shifts occur. However, it should be borne in mind that this is far from an average situation. Although the increases can be large, they occur in a minority of cases (although in Linux there are already incomparably more of them – see the test itself).

However, in the world of Windows, similar cases are minimal, and for an application load, more than a large cache pays extra kernels. Processor price monitoring sites have recently reported a discount on the 12-core Ryzen 9 5900X. Prices in our country also fell during April, although the historical minimum was reached last week, when the lowest price, according to the Heurek website, fell below CZK 10,000.

It is currently at the level of the previous week, ie less than six hundred higher. Even at prices starting at CZK 10,600, the Ryzen 9 5900X is a thousand cheaper than the lowest Czech announced prices of the Ryzen 7 5800X3D. Czech stores do not have it in stock yet. It was available on Germany or Amazon on the day of release and part of the following day ($ 449 for Amazon, € 489 for German stores), but has not been in stock since then and is waiting for the next batch.
