What? And in loses in others. Phoronix for example, and puget bench have a lot of lightly threaded tasks that alderlake wins. And not by a small margin in some of those

Indeed but why are you now picking arbitary wattage figures. We have 65w, 105w, 125w, 170w and 241w as like fixed delta points to compare. At none of those does the 13900k look to compete with Zen4 if you do direct power to performance from anything noted. Yes it is better than the 12900k but if the first point that 65w is 5k points behind then it takes 350w to get similar to the 7950k at 170w+ boost wattage extra, so around 240w max. It will still at least in this one synthetic test that everyone has been talking about show it off.

Steve shows that the 5950x is still the most efficient though in heavy mt workloads relative to performance. Would be interesting to compare mind what having it locked down in one of the eco modes does. It just seems the stock side is stupid high and way past efficiency curve. Which goes back to needing 350w from13900k and same issue for it to match AMD.

Yes software and all sorts otherwise are hugely different. I would be interested in why Zen4 struggles with some things like AutoCAD when it seems to boost fine and have better IPC but still fail. Is there still instructions or issues on AMD side because things have been so heavily optimised for Intel for last decade+ in that software as example? It relative to all the figures and IPC we know shouldn't be loosing out unless there are critical instruction paths that Ryzen doesn't work with as well compared to Ald & Rpt.

You can test at whatever wattage you feel like. Point is, even if the 7950x ends up being more efficient at heavy mt out of the box, it wont be by a lot. I expect the 13900k to score at least 35k at 240w, so the difference in efficiency will be literally negligible. Much smaller than it was between 5950x and 12900k with both at 125w, and that was already small
 
It's awfully nice of Intel to put the 5800x3d into its benchmarks, even though it shows the 13900k losing to the 5800x3d in gaming. Props to Intel for becoming more transparent to the detriment of their marketing.

Intel gave AMD very slow RAM in these benches but I'll let it go given the 5800x3d doesn't particularly care what RAM you have.

The 5800x3d is a thorn in Intel and AMD's side, more a problem for Intel though

Was it the batch with the problematic first dimm? Got a 2022 model that dont need, never used it from rma. Got the unify x and never looked back

Nov 21 batch, it wasn't as bad as some hence why I held on for a while, slot 1 was 2 speed bins lower so was governed by that and max stable was 6600 c32 but that took a lot of work and not particularly tight timings. Sticks will run 7200+
 
Well, the prices haven't increased for the 13700K and 13900K vs the 12th gen, so all the rumours that suggested otherwise were just plain wrong.

Don't suppose their investors will be too pleased.

There's gonna be some good competition between the 13700K and Ryzen 7700X. Realistically, lots will opt for the cheaper 13700KF and locked 13700, which will be late to the market.

Obvs people shouldn't be too surprised if next gen vcache CPUs blow everything else away in price and performance, for gaming.

It was clear from the AMD livestream that their power efficiency claims were smoke and mirrors.
Releasing new chips all with TDPs above 100W and telling us how efficient they are with a reduced 65W TDP was a bit strange.
AMD are forced to follow Intel and push the default settings well above optimal so that performance will look better versus the competition.
I don’t think Z4 is bad, it’s just that Z3 was a difficult act to follow and Intel have finally become more competitive.
Even Papermaster said that Z5 was the one that excited him, so I wasn’t expecting that much.

Whilst Z4 seems decent, with the higher power consumption and temperatures, I am wondering how much of a bottleneck the 3 and 4 nm nodes might be?
It seems as if TSMC will need different techniques rather than just shrinking the current node used here, which they have listed on the roadmap.
I don’t recall what and when or whether it’s too early to say what improvements will come.
Thermal density seems a difficult thing to deal with.

Around 100w-140w CPU package power(depending on voltage) is still pretty good, for the 8 core model, I'd say. Easily within the range of modern air coolers.

So this is where AMD does well, they are competitive with 8 cores. It's still not evident that more than this is useful to most PC/laptop users.

True, so maybe just think of the higher core counts as HEDT Lite.
At some point we will see 64GB modules giving 256GB support for the platform.
Plus with PCIe 5.0 giving bandwidth that seems irrelevant for consumers currently, it seems an unnecessary cost.

Anyone know what OC boards will be available such as Apex, unify at launch, would prefer 2 dimm boards

Dark maybe first for a change. Not like Vince is distracted by gpu’s anymore.

I’ll def let others test drive apex first from different batches. Bianbao says apex is fixed but we wil have to see if it’s QVL for 7200 A Die. If not, buyer beware.
