So that was Y Cruncher. a hundred billion, uh, BPT, uh, B, B, B, B, B, excuse me. It's hard to say. Um, but basically it, it, All it does is it's a compute benchmark. So it just wants as many threads and as high clocks as you can get. It's not memory bound at all. But the prior record at the time of that video was about 10 seconds. And that was a sub five second result.

And I see Jordan in the chat or as one of the audience members, he was running it with someone else in the room, Jeff from Graph Computing. And I was doing my video and I see him in my eye trying to wave this laptop.

Sort of three things here, if you don't mind. Um, What surprised me most about Turrent specifically was one, the fact that they hit five gigahertz on some SKUs.

On a server CPU. Yeah. But not just hit five gigahertz. Like I wrote in the article, Wendell from Level One Text in a essentially web server workload was hitting 4.9 gigahertz all core. That's nutty. That's utterly, utterly nutty.

Well, no, IBM C is the only, or really the only folks that do that sort of over five gigahertz consistently in server. Intel back in the day, if you remember those Black Ops CPUs, they were doing five gigahertz. And I believe that there was one, the last Oracle, Spark CPU, the M8, went up to five years. Did it really? But other than that, I'm having to draw upon some fairly niche CPUs here.

The fact that what is effectively a mainstream CPU can do this is crazy. But add on to that, just... The fact that Zen 5C, so sort of those compact cores, have the full 512-bit FPU, I think that that's really impressive considering that they're sticking 16 of them into a single CCD now.

Yeah, so here's the difference between Zen 5 and Zen 5C. From an architecture perspective, nothing. Until you hit L3, there's no difference. Now, are they on different nodes? Yes. Is there an Fmax difference? Yes. But the fact that they're still hitting 3.7...

f max so that's your top clock is really impressive and the no difference is i think you're on what three nanometer for the 5c and four nanometer for the yes and five is that right yes these are all tsmc obviously so on their c cores they jumped uh 600 megahertz so from 3.1 to 3.7 um god that is amazing yeah yeah and and i there was a good point made and i think the biggest jump

in recent AMD history in terms of the server performance. It's not Zen 4 to Zen 5. It's Zen 4C to Zen 5C.

I think that performance jump is far from... Like, I think that that's really, really exciting performance. But what I really like about Turret is not just that there's these big old high-end SKUs, the 128 and 192 core SKUs, but they've paid attention to this mid-range, right?
