Leaked Benchmarks Indicate IPC Rocket Lake-S to be slower than AMD Ryzen 5000

One of the primary benefits of the pending Rocket Lake-S series is the fact they're based on a new architecture, that architecture would offer better IPC. A website now has fired off tests at a Core i9 11900K measuring exactly that.

The end result is that, although an IPC increase definitely is measured, Ryzen 5000 remains to be the faster architecture. IPC byw ie the number of instruction-by-clock, indicative performance per core. The asia based reviewer compares the Core i9 11900K with the Ryzen 9 5950 and that reveals the existing Ryzen 5000 chips are about 6% to 10% faster than the Rocket Lake processors when both architectures run at 4 GHz and are limited to four cores and eight threads.

A 10900k at 5.1 only scores slightly higher, so Rocket Lake is pretty good considering its only 8 core, 16 thread.

Uh... 3090 is not the problem. I could order one immediately and get it in a couple of days from the store's own stock. I could even choose from several models. It's everything below the 3090 that's nonexistent outside of miners' caves and a few lucky real people here and there.

So true! I'd stated in other threads/forums that I can actually get an RX6900 XT or an RTX 3090 from some of the brick and mortar shops in the local tech mall. But, if you're aiming for the RX 6800/6800 XT or the RTX 3080/3070/3060 Ti, then you're outta luck. I've been informed that the recently released RX 6700 XT is also available (a guy posted that he'd gotten a Nitro+ RX 6700 XT for 741USD (present exchange rate), that's a smidgen above 50% price premium!!!).

I don't care about stock, never did

My 5900x is far from stock, and drawing about 320w full load :cool:

I'm between , im all in for extra free performance that i can get out of tuning. But when that comes with high expense of power and temperatures i'm out.

Just few weeks ago i tweaked the shit out of my 5600X and my B-dies , just to realise i don't need it "yet". So i run 5600X at stock + auto oc from asus , works pretty well , at least i can run 2000 FCLK without WHEA ( btw. it seems WHEA errors are casued by PBO boost algoritms when high FCLK is involed - above 1800).

You clearly don't understand the architecture Intel is working on. It isn't just atom cores.

What it is?

It clearly says gracemont cores. So if you expect anything better, good luck.

Gracemont is the successor of tremont, another atom cpu.
