It seems that with the Zen 2 architecture, AMD will reinforce some of the known weaknesses of Zen and Zen +: that the latency of the DDR4 RAM was much greater than that of its Intel competition or that the cache had problems Similar. In the case of Zen 2, AMD has decided to offer much lower memory latencies and double the L3 cache size of its processors to minimize the processor’s dependency on DRAM to access key data. In its last presentation, the company has referred to this new L3 cache as “GameCache”, linking this change directly with an improvement in performance to play.
According to this slide, the increase in the L3 cache has a greater impact on gaming performance than moving from a DDR4 2667 memory to a DDR4 3600. Any of the Ryzen users will know until now that the speed of memories is key to performance in games in Zen, so such an increase performance in Zen 2 when increasing the cache is somewhat impressive. With regard to the performance of the memories, to date 3200 memories were recommended for the first and second generation Ryzen, but for the third things change.
In this case, AMD goes on to recommend memories 3600 with CL16 timings, since they offer an ideal performance-price ratio. It is true that with its next processors it will be possible to install RAM with higher frequencies, but only when AMD enables its relationship between Infinity Fabric and DDR memory to 2: 1 mode, something that will increase the performance of the memories. Therefore, although AMD has set examples with memories at 4000 MHz for its third generation Ryzen, its speeds do not exceed 3733 MHz in 1: 1 mode. According to each case, the user may be more interested in giving priority to Infinity Fabric technology rather than RAM speed:
So, to summarize, how does it affect the players? First, that the third generation of Ryzen processors will have fewer memory limitations than the first two generations, with DDR4 modules at higher speeds and a larger L3 cache to keep the data as close to the processor as possible. AMD has affirmed that its processors based on Zen 2 will be much more compatible with more memories than the previous ones, correcting the problem of compatibility with many of them that there was. What a great time to review 5 keys on the new generation of AMD processors!
