Key Slides from Intel 13th Gen "Raptor Lake" Launch Presentation Leak
The most juicy bits of the Intel 13th Gen Core "Raptor Lake" launch press-deck just leaked, courtesy of Igor's Lab. They reveal the six SKUs Intel will debut the 13th Gen Core desktop processor series with, highlight key differences with the previous-gen "Alder Lake," and also detail what the new Intel Z790 chipset brings to the table. To begin with, the first-wave of 13th Gen Core processors will include six SKUs—the Core i9-13900K, i9-13900KF, i7-13700K, i7-13700KF, i5-13600K, and the i5-13600KF. The -K and -KF parts are identical to each other, spare for the lack of integrated graphics with the -KF ones.
Many of the key specs of these six SKUs were already leaked to the web along with those of several SKUs from future waves of 13th Gen SKUs, but this slide confirms a handful interesting specs related to power. The slide confirms 125 W as the Processor Base Power value for all six SKUs, 253 W as the Maximum Turbo Power value for the Core i9 and Core i7 K/KF SKUs; and 181 W as the Maximum Turbo Power for the Core i5 K/KF SKUs. This is a definite step up from the 241 W MTP for the previous-gen Core i9, 190 W MTP for the Core i7, and 150 W MTP for the Core i5. Of course, these limits are like a hedge blocking your path, you can relax them in the motherboard BIOS.
The next slide details the key differences between the 12th Gen "Alder Lake" and 13th Gen "Raptor Lake." The maximum core-count has gone up to 8P+16E. The P-cores are upgraded with higher IPC and L2 cache; the E-cores are upgraded with higher L2 cache. The PCI-Express I/O from the CPU is unchanged—16 PCIe Gen 5 lanes for PEG, 4 PCIe Gen 4 lanes for CPU-attached M.2 NVMe. In contrast, the Ryzen 7000 is confirmed to feature Gen 5 CPU-attached M.2 NVMe. The DDR5 memory speed has been increased to DDR5-5600 native, up from DDR5-4800.
The slide detailing the new Intel Z790 chipset is most interesting. The chipset bus is unchanged at DMI 4.0 x8 (bandwidth comparable to PCI-Express 4.0 x8). While the previous-gen Z690 puts out 12x PCIe Gen 4 and 16x PCIe Gen 3 downstream lanes, the new Z790 puts out an impressive 20x PCIe Gen 4 and 8x PCIe Gen 3 lanes. The USB connectivity is mostly identical except that the Z790 puts out five 20 Gbps USB 3.2x2 ports, instead of four on the Z690.
Intel is expected to announce the 13th Gen Core "Raptor Lake" processor series and Z790 chipset on September 27. The series will be expanded with more SKUs, and cheaper motherboard chipsets, such as the B760, later.

It will compete well.
For me though the ideal world be 12/24P Core's all fully power gated and 8 really quite low 15Watt total E core's.
And with decent scheduling that could be pretty unbeatable in All use cases and more useful yet efficient than anything even arm could manage in General use even cropped to I3 levels, IMHO.
As is, , it's going to be an interesting battle, likely better for me, the consumer, because it's going to be a closer fought marketing battle the present way it's panning out.
I'm with you Intel went overboard with E-cores for desktop Alder Lake, doubling that for Raptor Lake doesn't bring much to the table. But when you look at the block diagram of Alder Lake and see how little space the E-cores take, you can understand why they did it. At least for heavy multithreading, instead of having 16 P-cores that can't maintain max turbo for the duration of the job, you get 8 that can and a bunch of E-cores helping on the side. Still, very few things are in need of that many threads.
Raptor Lakes design had to have been completed around 2-3 years ago so around Zen2/3 given how much intel has improved in MT over the last 3 years mostly with AL they must have had a feeling Zen would continue to progress quite a bit
4 E-cores take only a little more space than one P-core. And on average, each E-core is only slightly slower than a Skylake core. It's hard to pass on that amazing perf/sq mm.
As with some others I would personally still prefer they went with a 12P core varient with no E cores but as you've pointed out they needed to compete in MT task intel is full of smart people I'm sure they know better than me.
Sapphire rapids might have also been interesting if it wasn't already a year late with no sign of when it will actually release.
Its your opinion. Dont know why u want more p cores, but i dont think u ll share with me like other guys :D
in the future there wont be less e cores. if amd jumps on this train with different core architecture.There ll be just more and more of e cores for us to complain about :D
For me, there is no application that would benefit from more p cores. If i need more cores, e cores are ideal.
Intel apologists seem very vocal around here in the “leaks” (ie, Intel PR) threads.
If they stole it or not ... everyone is using round wheels .. so whats you point ? :D
im not here to deffend intel. I just understnad why they did it. Sounds like u did not get it LOL
I don't know what you think Intel stole, and it doesn't really matter either way, but atom cores have been around for more than 10 years now. Also the Intel implementation is completely different to ARM. ARM uses small cores for efficiency, Intel uses them for performance. Completely different things
The simulations I run on CPU use every core I could throw at them and every Hz.
Given I also tend to run simulations of a different kind on the GPU simultaneously my load and temperatures are often maxed as would it be if I trebbled core's and GPU's.
Gaming is for p#£@y's :p :D I jest, but assuming we all just game and surf is arse.
This is a tech specialist forum, If I were just a gamer I would be here less.
Or I ll tell you, because you cannot pause that important NASA sim you actually now do. I ll burn hole to motherboard. Pin array would melt and GPU would warp... Ehm not rly. This glorious chip would thermal throttle to oblivion. And you ll use all 4Hz that would be left *48 ultra p cores LOL u are lost big boy old user
Then have a nice day talking to the wall kido.
but ist fine .. you just dont want to have a discussion :)oh now we are in the unicorn land that TDP is.... look up some AL tests and multiply it by 1,5 to get exactly what this other clown would like to have :D do you know how much bigger TR is my friend? its huge compared to desktop .. its a HEDTcan u read and understand words you are reading ? you can pack more E cores in the same size that P cores would occupy .. more E cores do more worky worky .. they eat less electrons = less energy wasted as heat => more energy used for switching other E cores .. they are more efficient than mighty P cores ... they are better for highly paralelized workloads ... got it ?
With Alder Lake they climbed far up the power wall, but Raptor Lake will have improved power efficiency over Alder Lake as they'll have to clock a little slower and reduce volts to power the +8 E cores.
Chips & Cheese has analysis on improving & comparing ADL efficiency with Zen2 to aid tuning for heavily loaded systems, the motherboards set tau so the CPU never drops to the nominal TDP.Because they can use them for foreground tasks as well; W11 in balanced mode reserves P cores for foreground jobs, justifying a marketing narrative is the E cores are efficient background processors.
For the reality of the power inefficiency of Alder Lake and how to tune it into sweet spot suitable for heavily loaded systems, Chips & Cheese has an analysis article comparing the behaviour of the P & E cores.They should be explaining how cache light E cores with poor AVX performance are a good fit with creator benchmarks. So a design feature intended for battery saving on mobile, has been turned into moooaaahhhhhrrrrrrr core are better, aimed at the common reviewers MT benchmarks. Cache & Memory intensive MT is just ignored, as is power efficiency.
You have to edit vmx file to tell VMware not to use e cores if you want to utilize p cores. That makes paying for e cores a waste of money if what you're doing in VMware is the reason you need mt performance.
I have a filling that by the time AMD will implement it`s e core solution (around ZEN 5) there will not be any argue about it, just as having HT is just better than not having it.
Time will tell...
