Intel Raptor Lake and AMD Ryzen 7000 They promise to star in the most interesting train wreck. Both companies, each with their own strengths and limitations, seem to be in good time, so much so that the next generations of their processors aim to Similar instructions per cycle (IPC) as revealed by @OneRaichu Twitter account.

@OneRaichu posted via tweet alleged performance tests of both the AMD Zen 4 architecture used by the AMD Ryzen 7000 and Raptor Cove processors, the high-performance cores found in the K and i7 series and newer Intel Raptor Lake processors. Also compared were Golden Cove, a high-performance Alder Lake core architecture, and Gracemont, a low-power core architecture used in Intel’s Alder Lake and Raptor Lake processors.

Running a performance test SPEC CPU 2017 Rate-1 (SPECCPU2017 Rate-1) with a clock frequency of 3.6 GHz it can be seen that Raptor Cove (RPC), Golden Cove (GLC) and Zen 4 (RPH) get similar results.

@OneRaichu explains that the Zen 4 has a large cache configuration that makes it less DRAM dependent. On the other hand, he noted that the higher latencies of DDR5 and Gear2 mode can result in 15 nanoseconds of latency and almost a 2% reduction in IPC compared to DDR4-3200 JEDEC. However, the published data is from JEDEC-DDR5-4800 and here Raptor Cove shows a slight advantage against Zen 4 and Golden Cove.

after changing the memory DDR5 on 4,800 MHz to others of the same type, but on 6000 MHz, the filter performed multiple tests. WITH SPECCPU2017 Rate-1 Again we see the Raptor Cove and Zen 4 achieve similar results, the former being slightly higher. This time Gracemont (GCM-12 and GCM-13) joined the party with a slightly better result at Raptor Lake than at Alder Lake, possibly due to frequencies.

In the RAM test, we again see the same scenario as with 4,800MHz. Raptor Cove wins by a bit more than Zen 4, which is also placed below Golden Cove. Once again, Gracemont’s implementation at Raptor Lake outperforms Alder Lake.

as we see both architectures, Zen 4 and Raptor Cove, show similar IPC levels. Of course, it’s important to keep in mind that this is an alleged leak and that we should wait until the Raptor Lake and Ryzen 7000 processors start rolling out, as we may be in for a surprise.

AMD seems to have everything on track for the Ryzen 7000, but Intel is giving lime and sand by announcing on the one hand that Raptor Lake will reach 6 GHz at factory settings and 8 GHz with overclockingbut on the other hand, he indicated, albeit very clearly, that he decided to recycle the Alder Lake technology for the non-K models of the Core i5 series and below.
