True but still not cheap.
Flavors less important than the base node. It isn’t N6 cheap, but for the premium market the N4 family is probably the highest bang for your buck right now. N3E plausibly better depending on what you’re doing and with enough volume, but like N4 and N4P are being used in midrange or entry level premium smartphones now, so.

But yes I agree it’s not dustbin. Die size did increase too for Strix, should be 220-230mm^2? Vs 178 for Phoenix. But they’ll have Kraken (4+4) as a separate part later to get the entry premium and cut down on that area.

This is hilarious to watch.

Do none of you remember the slow creep up of IPC from Sandy Bridge to Skylake, and the complete stagnation after that for years? 15% increase is fine, good grief.
People have forgotten everything, but on purpose because there are no other options.

Even this has already been forgotten, even though these are grim facts.

Intel 12/13/14 Gen CPU-s, the same CPU architecture with the addition of more L2+L3 cache(13/14 Gen)+drive the CPU frequency sky high, and AVX512 is dead!

It's OK, but not good considering it's launching pretty close to 2 years after Zen 4. Will be lucky to maintain the status quo against Intel's next gen and ARM CPUs are definitely going to eat some of AMD and Intel's lunch.

At this level of performance, Zen 5 ought to have been a quick follow up to Zen 4 like Zen 3 was to Zen 2.

It is good. Excluding the hype, many of us were expecting a larger increase as Zen5 should have been a tock (every other zen iteration). It's not so compelling going from Zen4->Zen5, but ppl (such as me), on Zen2/3 will be seeing substantial gains when upgrading to Zen5 and AM5.

No, Geekbench is fair too. Wider code footprint in some ways? Both are fine. No diss to Specint tho.

Bruh?

Look above — not Yo/Y but this year. And Arm has been barreling forward for a while now. X4 was a 10-12% IPC improvement and really close — mid single digits — to Firestorm IPC, closer than Zen 5 for sure. X3 was around 5-8% gains I think and even then was doing rouuughly mobile Zen 3 ST at 5W total power in 8 Gen 2 or 9200, and ofc at less frequency.

It’s honestly strange people are so ignorant about Arm’s cores.

Matching Apple is a high bar on IPC, but even more so with power as the X4 showed, it’s true they’re not A+ cores and probably Qualcomm will have some power leads I can see too.

But “even” being a Firestorm Walmart/generic core like the X4 was (hitting 1600-1690 GB5 for ex, or at 2300-2350 in GB6) with worse power characteristics than Apple — but still doable in phones — is self evidently better than what AMD/Intel could offer in PCs for a similar perf.

The sneering about Arm’s Cortex IP is fair vs Apple and arguably QC, but not vs AMD and Intel anymore save probably some server stuff.

Their own SPECint numbers show noticeably lower IPC. GB6 is not a bad bench, but there are multiple reasons SPECint is considered the standard as far as generalized benchmarks go. If SPECint is the standard for everyone else, it should be for Arm as well.

~15% is in line with my expectation, but there were few here boasting >30% and at $999. I wonder these AMD hype is done on purpose? This tend to happen every AMD release. For me the real disappointment is, this is the 4th generation with 16 cores. Time to move on from it.

I do think it’s partially being pumped by the 50% increase in SIMD registers to be fair, but that’s still quite valid. And only partially.

They had like a 34% IPC lead in SpecInt over Phoenix with the X4 (8 Gen 3).







And I don’t think AMD got 16% IPC in SpecInt 1T did they with Zen 5? Was maybe slightly higher than Arm’s, like 10% vs 5-6%.

I was expecting normal Zen results that is about 20-25%. So 16% with a 300MHz clock boost would have worked. But it is the first miss for Zen - no clock rate increase and first time under 20% 1T performance improvement over predecessor.

But being late is normal for Zen, all of them were except Zen 3.

We don’t have any SPECint reference for Zen 5 yet. In the past, AMD’s IPC number has lined up closely with the SPECint results despite them showing weird benchmarks in their IPC comparisons but, as I already said, we’ll obviously need 3rd party reviews with SPEC to confirm this with Zen 5. The point is, given the standard we’ve used at least for several generations now, AMD is not lagging in IPC gains on a CAGR basis and may actually be slightly leading the industry in this regard for the last few generations, depending on how independent reviews turn out for the latest cores. So despite the hype train crash, they’re still doing pretty good in this regard.

should be 220-230mm^2?
225mm² for Strix Point

I'm still waiting for confirmation (Xino), but rumor mill says that Kraken isn't that smaller than STX actually. Circa 190 - 200mm² somehow.

NPU is the same, so that's a fixed area cost to be paid. But KRK sports 4 Zen 5 cores with 4 less Zen 5C cores and a half-wide GPU. So something doesn't add up.

I only now catch up to over 20 pages, and turns out, this was accurate.
And we all know what happens with AMD Hype Trains.

I guess it comes from being promised 30-40% IPC increase .

You gotta look who is promising next time.
I think there is a level of justifiable disappointment, though, because it is the weakest Zen yet regardless of the hype train.
Don't believe the rumors spread by... Intel engineers simply.

Same thing happened for RDNA3, same thing happened for Zen 5. Which is why I was cautious believing them.

The thing that impresses me most with AMD through the Zen era thus far is the relentless increase in IPC through the generations. 16% here, 19% there, the release cadence and performance increase just march along.

They blew the lid off core count with CCD's and 16 core parts many years ago and have stuck with that winning formula, which includes continual IPC increase and high efficiency.

They are a moving target for Intel and Intel can't quite get a bead on them. It must be incredible challenging for Intel that AMD refuses to stall or stumble.

Meanwhile in an attempt to complete Intel has moved to hybrid designs, moved to tiles, and pushed clocks and power into the stratosphere to stay competitive. Say what you want about "16%" but I'm sure Intel is mighty impressed (and concerned).

225mm² for Strix Point
Yeah. For example that’s 32% more area than SDXE (170mm^2 ish) which has 12C of similar performance, almost certainly much better battery life, similar NPU power, similar IO and media engine (actually tbf AMD likely has an encode lead on frames?). GPU though with RDNA3.5 is a raw perf and compute win for AMD and worth same area except I’m not sure how well it’ll scale down.
I'm still waiting for confirmation (Xino), but rumor mill says that Kraken isn't that smaller than STX actually. Circa 190 - 200mm² somehow.
Yea. Well, what matters also is what they charge for it. Markups for the top parts usually higher.
NPU is the same, so that's a fixed area cost to be paid. But KRK sports 4 Zen 5 cores with 4 less Zen 5C cores and a half-wide GPU. So something doesn't add up.
hmmm.

3700-4000 GB6 1T around 11W platform is honestly ludicrous. I will bet everyone here Lunar Lake comes in 2800-3200 range at peak and uses more power than that by probably a factor of 50% if not 100%.

Apple M4 supports the SME, but all other platforms do not. As a result, you can't compare those scores. That's what Geekbench says in their release notes for 6.3. From my perspective, GB6 is a terrible benchmark. The previous version is closer to the truth.

I think AMD Ryzen HX 370 will be close to M3 Max in terms of performance and power consumption.

Geekbench has AVX512 backends too, and I don't see you complaining about those being x86-specific.

The larger lesson here, I think, is that benchmarks with platform-specific code, for anything, have limited value as a comparison point.

Well, AMD/Intel also get a boost in that subtests due to AVX-512, so if you want to exclude Apple SME from the comparison, you'll have to exclude AVX-512 from x86 parts to keep the comparison fair.

Right. A benchmark with hand-written backends (whether assembly or intrinsics) tends to become a benchmark of the quality of those hand-written backends, not of the quality of the hardware or the compiler.

Intel has no avx-512 from alder lake on. Unless you are talking about server chips. And excluding avx-512 is fair ? Not for those of use that use it, and need it.
