Not quite Coffee Lake performance levels (130 vs 150 points on the single core floating point performance test), although as an engineering sample with slow RAM it's too early to draw apples to apples conclusions, but it is nice to see another large IPC gain, making it nearly 25% faster IPC wise than first generation Ryzen, cutting the IPC difference to about 15%, with rumors suggesting the final product will be 10% slower if not even closer to parity.
And, clock for clock, officially over 100% faster than Piledriver, so all you people still using Socket AM3/+ systems...the time to upgrade is nearly upon you.
Zen 2 Engineering Sample
The engineering sample's product code purportedly identifies this engineering sample as a Matisse processor with the "H2" designation at the end of the product string. The chip was also tested on an AMD Myrtle-MS development board, which is known to be an AM4 test platform. That means this processor is designed to fit within AMD's existing mainstream desktop lineup.
The test result lists the 12-core 24-thread engineering sample with a 3.4 GHz base clock and a 3.6 GHz average boost during the test. The product identifier lists the peak boost clock as 4.7 GHz, and the TDP rating as 105W. We're expecting higher turbo speeds from the third-gen Ryzen processors, the current gen tops out at 4.3 GHz, but early silicon typically comes with dialed back frequencies as vendors fine-tune the design. In other words, these results likely aren't representative of the final clock speeds.
The UserBenchmark System Memory Latency Ladder quantifies the latency of L1, L2, and L3 caches of the test sample, and the decline at 32MB indicates the engineering sample comes armed with 32MB of L3 cache. The test system is also configured with DDR4 Hynix memory running at 1,333 MHz, which equates to 2,666 MHz.
The chips' single-core floating point score is also telling - at 130 points it outstrips a current-gen Ryzen 7 2700X (at roughly the same clocks) by ~13%, an improvement likely born of improved instruction per clock (IPC) throughput. That implies this chip comes with the Zen 2 microarchitecture.
