Intel Core i9-13900K and i5-13600K Review: Raptor Lake Brings More Bite
by Gavin Bonshor on October 20, 2022 9:00 AM ESTGaming Performance: iGPU
Despite updating the main bulk of our CPU test suite for 2023 and beyond, we've not had a chance to test every integrated graphics chip in our stack of CPUs. As a result of this, we've included limited results for our iGPU-based gaming tests, although it is more than enough to get to grips with improvements in Raptor Lake performance.
As a reminder, We are using DDR5 memory on the Core i9-13900K, the Core i5-13600K as well as Intel's 12th Gen (Alder Lake) processors at the following settings:
- DDR5-5600B CL46 - Intel 13th Gen
- DDR5-4800 (B) CL40 - Intel 12th Gen
All other CPUs such as Ryzen 5000 and 3000 APUs were tested at the relevant JEDEC settings as per the processor's individual memory support with DDR4.
Final Fantasy 14
World of Tanks
Borderlands 3
Far Cry 5
Grand Theft Auto V
Strange Brigade (DirectX 12)
For both 13th and 12th Gen Core series processors, Intel is using the Xe-LP based 770 HD graphics processor. This means the overall integrated graphics performance between the two is almost identical.
In our integrated (iGPU) graphics testing, the power of Intel's Raptor Cove cores combined with more E-cores does show a distinct, but negligable advantage when using Intel's 770 HD graphics. This advantage is clear in Final Fantasy 14 where more cores and more CPU power are advantageous for performance.
Looking at the iGPU performance of both the Core i9-13900K and Core i5-13600K in our other tests, the Core i9 performs best out of Intel's chips, but in games where graphical power is required, the AMD 5000 series APUs do come out best. The Core i5-13600K also performs marginally worse than the Intel Core i9 12th Gen series, but this is to be expected.

The 7950X outperforms the 13900K from 65W to 185W by substantial amounts: https://www.youtube.com/watch?v=P40gp_DJk5E (19:00, Cinebench R23 multi)It also seems to use less power at lower temps in gaming (23:00, Cyberpunk 2077)
That's probably not the end of the story, but Zen 4 is clearly doing better out of the box. Good news for Dragon Range buyers in 2023. Reply

Very happy that Raptor Lake is super competitive to AMD 7000 series! AMD has to lower it’s high end pricing now for both it’s chipset and retail pricing. Let the price wars begin after Thanksgivings. I expect the 7050X to go from $699 to $499. X670E boards will be the same price as the Intel equivalent models! 😁👍 ReplyDrazick - Thursday, October 20, 2022 - link
Could you build / compiler the SPEC tests with AVX512 flags for the Ryzen 7xxx? ReplyRyan Smith - Thursday, October 20, 2022 - link
It's on the to-do list. Though we're not expecting a significant change in performance. ReplyKangal - Thursday, October 20, 2022 - link
Any plans to test these in thermally or energy-constrained limits? Like with Air Cooling, or certain Watt limits?Or perhaps, how will Zen4 on laptops compare to Intel's RPL-equivalent on laptops...?
From here it looks similar to Zen3 vs Intel 12th, or Zen2 vs Intel 11th. That AMD is competitive in multithread and better efficiency, and Intel only remains competitive by expending alot of power, and it's mostly for the single-core.

Yes. Performance testing at lower power levels is also on the to-do list. We had a chance to play with eco mode a bit for the Ryzen review, but didn't get to do something similar for Raptor Lake. ReplyKangal - Friday, October 21, 2022 - link
Oh nice, will be waiting for that next article to drop. Cheers!Reply

@Ryan: How about testing idle power and realistic day-to-day use cases? I can only find this kind of review for 12th gen vs Zen3 and not 13th gen vs zen4. Would be really nice to have the numbers for 13th zen vs zen4.Here is a link to the review for 12th gen vs zen3: https://youtu.be/4F2z3F64o94 Reply

@Ryan, I am not sure about it.I think enabling AVX512 on Ryzen will have a great effect on the FP tests of SPEC. Reply

There wasn’t a delay when one of the rendering apps got AVX-512 support several years ago. Reply
