Alder Lake-S leaks
- Thread starter Grim5
- Start date
DDR5 4800 is just the starting point.
DDR5 6400MHz is already been tested and passing, so the speeds will ramp up massively!
Remember DDR4 first hit at like 2133MHz with very poor latencies. We now have DDR4 at 4000MHz plus with tighter latencies.
DDR5 will be hitting some big speeds for sure, give it time.

Thanks was going to buy DDR 5 at launch but will probably give it time like you suggest. Maybe look back at buying some in a couple of years when it matures.

Decent improvement already around launch with that 6400 cl36, guessing even just 6 months should bring even better again.DDR5 4800 is just the starting point.

By the time AM5 & Raptor Lake rolls around there should be some pretty good speed DDR5.

I want the 12900k myself but I'm not go not pay scalpers prices for it and the motherboard ram and cpu.
Info leak from Chinese guy who uploaded benchmarks and photos of the 12900k
list of claims:
* big.little doesn't work in windows 10, in windows 10 half the 12900k cores get disabled
* All new boards supports only DDR5 or DDR4 exclusively, nothing hybrid
* PCIe5 on z690 is only supplied to 1 GPU slot, all other board slots and m2 connectors are PCIe4. You likely have to wait for Raptor lake to use a PCIe5 Nvme drive
* Maximum temp before throttling is 108c. z690 chipset doesn't run hot, all boards feature passive cooling
* Disabling the Little cores in the Bios does not lower power draw, but allows the Big cores to clock higher.
* 12900k is able to reach 5.2/5.3ghz all core OC on the big cores. Little cores can't be OC'd
* RAM performance on games isn't great with DDR5. To beat 3600 CL14 DDR4 game performance he had to overclock his DDR5 kit to over 8000mhz. Generally observed that latency is 40% higher on DDR5 vs 4.
* With little cores disabled, big cores OCd to 5.3ghz and DDR5 at 8000mhz OC - he observed 50fps increase in counter strike global offensive vs the 5950x with 3600 CL14. This means the 12900k beat the 5950x by 7% in this game

edit: should mention these tests are before Microsoft fixes the amd L3 cache bug so amd performance may be lowered due to that

If all this is true im saying bye bye to Alder lake and waiting on Raptor lake. No interest in upgrading to W11 atm, the cost of the upgrade is phenomenal.

Leaks leaks I want gaming benches...
How about leaking dripping gaming benches?

Again looking sort of like the 10900K, it offers best possible gaming performance with caveats :
Huge cooling on CPU to support overclock 5.2/5.3 all core power draw
High end mem 3600 C14 or DDR5 8000+ wasn't that 2v needed for this reported ?

Well yes, but all the suggestions seem to be to OC it the best you switch off the little cores. how easily this can be done, and if it can happen on the fly in windows 11 remains to be seen.
7% CSGO increase with ddr5 superclocked to 8k and the processor OCed to all core 5.3, one would assume custom loops etc.
Yet we might find that with normal DDR4 on a DDR4 board that perf is just as good, or I would suspect better.
I keep seeing that, but surely as long as there is a x16 PCIe 4.0 slot all it takes too run NVMe at 5.0 speeds is to put the card which can't benefit from PCIe 5.0 (the GPU) in the PCIe 4.0 slot, get an adapter from x16 PCIe 5.0 to 4 X 4 PCIe 5.0 M.2 NVMe slots and you're sorted.
Once they're are any decent PCIe 5.0 NVMe drives.
I think this is just retailers and supply and demand, the 5600x started rising steadily in price about 3-4 weeks ago. I don't think ADL launch will do much for the 5600x, I suspect ADL parts will be shortish supply, MB's will be expensive. I'm thinking the ADL parts will simply slot in the price performance curve relative to the AMD counter parts, I can't see an Intel launch dramatically improving the cost per performance ratio, ie selling much faster systems at less than AMD, hope I'm wrong though.
