Game test:

In order to ensure the fairness and uniformity of the test, the demo and frame number statistics that come with the game are used, and each game runs the demo five times, and takes the average value. Invalid, make up the test once. If the frame number statistics of the game itself include decimals, the decimals of the corresponding number of digits will be reserved, otherwise, they will be rounded up.

In high-frame games that focus on more CPUs, such as Ashes of Singularity, CSGO, etc., the improvement of 13900K compared to 12900K can be 10%+. If the graphics card is replaced with a higher-end model, then this gap will continue to be enlarged.

Intel's magic modification of the Ring bus reduces the access latency of Ecore. At the same time, the Ring frequency of RPL is decoupled from Ecore, so there will no longer be the problem that the Ring slows down significantly when the ADL is loaded with small cores.

However, the RPL will still slow down. The 13900K will be downclocked from Auto 5000MHz to 4600MHz, but the improvement is much larger than that of the 12900K, but it means that you can still improve the game performance by turning off Ecore.

Energy efficiency test:


We first performed a simple power consumption test:

In the AIDA64 FPU scenario, the power consumption of 13900K DDR5 is about 253w, and the core frequencies at this time are about *** and ***.

In the Z690 motherboard and the August BIOS, the power consumption after unlocking the power wall is about 343w, the voltage at this time is around 1.4V, and the core frequency is about 5.5 GHz for the P core and 4.3 GHz for the E core.

Conclusion:

One year after the release of the Alder lake product, Intel obtained a new generation of Raptor lake with higher frequency and better energy efficiency by further relaxing the CPP's 10nm Enhanced Super Fin plus (Intel 7+) process. By increasing the frequency and the number of small cores, while increasing the single-threaded performance by about 12%, the multi-threaded performance has been greatly improved to compete with the new Zen 4 released by AMD this year.

No matter who will die in this generation and who will become the king of single-threaded/multi-threaded performance in this generation, I think this should be the best era of semiconductor development in the past decade.

Because this is the most competitive era, it is also the most beneficial era for consumers. With fierce competition, there will be continuous progress, no matter what the field is. 作者:ECSM_Official https://www.bilibili.com/read/cv18648273 出处:bilibili

It's pretty ironic that the "new" Raptor Cove gained less perf/clock than the reused Gracemont. Even similar frequency uplift.

Gracemont cores on RTL are benefiting more due to Double L2 and higher speed of the cores and Ring. They were very constrained to begin with.

I am dying to see how that compares to a retail 7950x, but in 9 days we should know. That will save arguments.

But I must says, 42% boost for 45% more power and 343 watts total seems insane. How would you cool that ? AIO are only 250 watt I think. Custom WC only ?

I hate that we have a clear language barrier with the Author of the Tests..

So am I correct to say 42% MT boost for 45% more power consumption(When unlimited power mode)? right?
That s 43% more power, from 240 to 343W, so basically the same perf/watt at these conditions than ADL.

It looks like about a 42% boost when both are in unlimited mode. Though I don't see a mention of how much power the 12900k consumes in that scenario. But out of the box, we'll probably see a smaller performance gap but greater efficiency improvement.

TLDR:

13900k compared to 12900k:
  • ~12% higher ST / gaming performance
  • ~ 42% higher MT performance at "unlimited mode"
  • Power usage have increased from 236w to 343w to reach performance numbers above

  • P-core IPC increase is basically nothing ~1-3%
  • E-core IPC increase is ~6%
  • Most of performance increase comes from higher clockspeeds
Seem to be higher memory latency in aida because of the more stops on the ringbus, but the L1, L2 and L3 bandwidth is increased substantially.
Ecore only downlock the ringbus to 4.6ghz instead of 3.6ghz when they are in use

The improvement is mainly brought by the amount of cores, RPL limited to 8 + 8, that is the 13700K, would use about 210W at same MT perf than the 12900K@240W according to Intel s process perf/watt improvement wich is stated at 10-15%.

Where's that 10-15% from?

Google translate:

On September 28, 2022, Beijing time, after eleven months, Intel released their new generation of desktop products, Raptor lake-S-Raptor Lake. (CPP) further relaxed from 54 nm to 60 nm to get the ultimate 10nm process, finally offering a Pcore frequency in excess of 0.5 Ghz compared to the Alder lake series. At the same time, Intel doubled the Ecore in i5 i7 i9 products and provided more L2/L3 cache to improve application and game performance, finally taking performance to a whole new level.

Again, where's the 10-15% efficiency claim coming from?

And as for that bolded quote, iirc Intel's pretty much been exclusively using 60nm CPP since at least Tiger Lake. Don't think there's been any change for Raptor Cove.

The slide was undoubtly posted in this very thread, i tried to find it at Computerbase but they dont always publish all slides in their articles even for big events, FI some slides from AMD s presentation were not published, some can be found at AT...

Thanks for the summary.

I almost nailed it in my perf. projection here: bit.ly/3PEY8cM
I predicted 15% better ST performance for 13900K vs 12900K and then end result is ~12%. I estimated that MT increase will be 49% and the preview shows 41% which matches intel's info from the last conference they held. Overall, I missed the ST/MT performance by 3/5%.

I'm pretty confident now that ST will be a ~tie between 7950X and 13900K and 7950X should win the MT by 5-7%.

Regarding perf./watt in the "unlimited" mode, in MT workloads it should be 1.41/343W Vs 1/236W. So a tie more or less (~3% difference)

Doesn't that indicate that they were able to flatten their V/F curve a bit? If so, it should be quite a bit more efficient than ADL at reasonable limits like 251w or even 125w.

Both Alder Lake and Raptor Lake ostensibly use the same Intel 7 process. If there're differences, Intel hasn't said.
I m about sure, in CB R23 8 e cores would add about 8800 pts as well as 50W at same process and frequencies, to dial down the whole from 290W to 253W would require 14.6% perf/Watt improvement.

Since the 12900K@240W score 27281 pts this would put RPL at around 36000 pts@253W, that s about what is leaked by some people who have the chip in hands.
