An alleged AIDA64 cache & reminiscence benchmark of the AMD Ryzen 9 7900X “Zen 4” Desktop CPU has been revealed by leaker, HXL, exhibiting a 50% bandwidth acquire over Zen 3.

Alleged AMD Ryzen 9 7900X Zen 3 CPU Offers Over 50% Higher Bandwidth Than Zen 3

HXL appears to have managed to get his fingers on what appears to be the AIDA64 cache and reminiscence benchmark results of an alleged AMD Ryzen 9 7900X Desktop CPU based mostly on the Zen 4 structure. The benchmark particularly exhibits the L3 bandwidth and latency figures that are seemingly going to get a a lot greater efficiency bump than Zen 3. And earlier than we get into the numbers, let’s discuss concerning the specs of the Ryzen 9 7900X which we leaked yesterday.

AMD Ryzen 9 7900X 12 Core “Zen 4” Desktop CPU

The AMD Ryzen 9 7900X, which because the identify suggests, would come outfitted with 12 cores and 24 threads. The CPU comes with a good larger base clock of 4.7 GHz and a lift clock adjusted at 5.6 GHz throughout a single core. The CPU retains its 170W TDP and will get 76 MB of cache (64 MB L3 + 12 MB L2). The CPU can be positioned in the identical ballpark because the AMD Ryzen 9 5900X however with a CPU efficiency that will shake the bottom from under the Core i7-12700K.

Now coming to the benchmark, we get 1494.8 GB/s in Memory Read, 1445.7 GB/s bandwidth in Memory Write, 1476.6 GB/s bandwidth in Memory Copy, and a latency of 10.1ns. Now we do not know what sort of specs all the system was working however it needs to be utilizing the DDR5 DRAM.

For comparability functions, we shortly put collectively our check mattress and ran the Ryzen 9 5900X, Ryzen 7 5800X3D, and Core i9-12900K by means of the identical assessments. The Ryzen platform was working DDR4-3800 whereas the Intel platform was working DDR5-6000 reminiscence. The outcomes are under:

As you possibly can see within the benchmarks, the alleged AMD Ryzen 9 7900X 12 Core CPU delivers a 47% enhance in L3 bandwidth over the Alder Lake and over 50% enhance versus its Zen 3-powered predecessor. The distinction widens within the L3 copy metric where the chip is sort of 3 occasions quicker than the Alder Lake CPU. In latency, the chip delivers the bottom timing of all with an interconnect pace of 10.1ns whereas the Alder Lake CPU has a time delay of twice as a lot at 21.8ns. Do be aware that in latency figures, we’re speaking timing, and the decrease the higher.

Alleged AMD Ryzen 9 7900X “Zen 4” CPU Offers Over 50% Cache Bandwidth Versus Zen 3

The AMD Ryzen 7000 CPUs will provide as a lot as 80 MB of cache in comparison with 68 MB of complete cache on Raptor Lake CPUs so they could retain larger bandwidth and higher latency in cache-specific benchmarks. With that mentioned, we acquired the launch approaching quickly subsequent month with a remaining unveiling of the specs and costs later this month.
