A set of benchmarks have appeared online for what appears to be Intel’s 13th-generation Core architecture, known as Raptor Lake, which will soon vie for a spot on our list of best gaming CPUs. The results, which appear to be from a submission to the SiSoftware database, appear to show the chip’s hybrid architecture gives a Ryzen 9 5900X a run for its money, though there are no direct apples-to-apples comparisons to be made between the chips chosen due to differing core counts. Also, these chips will face off with AMD's Ryzen 7000, which isn't on the market yet. Take the news more as an indication of what to expect, rather than solid fact until official benchmarks can be verified.

The benchmarks use the 5900X - a 12-core, 24-thread chip - alongside Intel’s 11th and 12th-gen i9s, one an 8C/16T and the other a 16C(8+8)/24T hybrid design. The Raptor Lake contestant has more of the efficiency cores than the 12th-gen CPU, boasting eight power and 16 efficiency cores, for 32 threads overall and likely the same chip that leaked earlier this year.
Little wonder, then, that it comes out in front. The interpretation of the numbers is also kind to the Raptor Lake chip: “With non-SIMD code, we see huge performance uplift in both integer (old’ Dhrystone) and floating-point (old’ Whetstone) of 33% to 100% over ADL [Alder Lake] that help push (way) past even AMD’s Zen3 with 12 big cores! The extra eight Little Atom cores greatly help here.
“Thus for normal, non-SIMD code – RPL [Raptor Lake] will perform greatly and provide a great upgrade over ADL.”
This looks good for gaming, but is not the full story, as the second set of results, using vectorized SIMD code, show. Raptor Lake comes in second to Zen3 in three out of four tests: “With heavily vectorized SIMD workloads RPL cannot beat ADL by more than 4-6% and thus generally even lose to the AVX512-enabled RKL [Rocket Lake] with just 16 threads (vs. 32T on RPL). This shows just how much AVX512 can help despite the extra power required – and here it is hugely missed. However, AMD’s Zen3 (5900X) with [fewer] threads (24T) but 12 big cores (vs. 8C + 16c) still beats RPL by a decent margin.”
The ‘decent margin’ here being almost 900 points in the Integer SIMD test, which sees the 13th-gen Intel chip come last in the comparison.
The preview of the new chips and its conclusion are worth reading, bringing together threads such as software support for hybrid architectures, the effect of cache levels on performance, and whether Socket 1700 PCs are worth upgrading to, given that Meteor Lake will use a different interface. Otherwise, Intel’s 13th-generation Raptor Lake architecture seems like the multi-threading monster we were promised, but only when fed the right type of code. In the end, we won't know how the chip truly stacks up until we can test them ourselves for the CPU benchmark hierarchy.
Also, the 5900X is nowhere near its MSRP now. You can always find it at or under ~$420 (£360 in the UK). We have Alder Lake to thank for that!
To me, this is just small confirmation Meteor Lake will be trading blows with Zen4. Which is good.
not super exciting to see a 13900 (basically the flagship) only beat it by a small amount and they also get crushed in vector vs not flagship previous gen.
Also have to remember its (likely) ddr 5 vs ddr4 in the benchmarks (as zen3 doesnt use ddr5)
Hope they can get better performance thoguh as want competition.
If you can't provide it; then all you've got is hot air & supposition.
That said I didn't expect anything more than a few % in IPC from Raptor Lake vs Alder. The boost was always going to be in additional cores and some cache rework - L1 and L3 look like they are the same just more cores, L2 though is different. The DDR5 memory controller should be improved as well.
but we all know how badly ES or new CPU support in general is for the apps that read out this info.
We can hope that it was really running at that speed because that would mean that the end product would be very nice but it's not a sure thing.
