If malicious program has access to GPU directly or via some buggy interface, the whole system is at risk. There is no "safe" GPU virtualization like there is with CPUs.


Yeah, why do they change options so often. They should keep some backward compatibility, qemu is not a new project.


> why the milestone isn't something classically hard but easily verified

They're far from being able to do any such thing, so posing such milestone would make the field look stagnant and thus be a bad marketing and hurt the money stream. The "milestones" are chosen so that they are plausibly reachable in short time relevant to patrons/investors, because people working on this need to constantly demonstrate progress.


> All the manipulations the Americans imagine are contradicted by events.

What does this mean?


WMD in Iraq is an instance of this.


> the ideology collapsed, economy doesn't perform

Economy doesn't perform, but ideology has collapsed only in minds of ordinary people. Politicians, stakeholders and various media outlets are very much invested, and still push that the current course is the only correct way and the bright green future as designed is unstoppable. Reminds me of the arrogance of the ruling party slogans from before 90s.


Too late, and it has a bad rep. This effort from Intel to sell discrete GPUs is just inertia from old aspirations, won't really help noticeably to save it, as there is not much money in it. Most probably the whole Intel ARC effort will be mothballed, and probably many more will.


What's the alternative?

I think it's the right call since there isn't much competition in GPU industry anyway. Sure, Intel is far behind. But they need to start somewhere in order to break ground.

Strictly speaking strategically, my intuition is that they will learn from this, course correct and then would start making progress.


The idea of another competitive GPU manufacturer is nice. But it is hard to bring into existence. Intel is not in a position to invest lots of money and sustained effort into products for which the market is captured and controlled by a much bigger and more competent company on top of its game. Not even AMD can get more market share, and they are much more competent in the GPU technology. Unless NVIDIA and AMD make serious mistakes, Intel GPUs will remain a 3rd rate product.

> "They need to start somewhere in order to break ground"

Intel has big problems and it's not clear they should occupy themselves with this. They should stabilize, and the most plausible way to do that is to cut the weak parts, and get back to what they were good at - performant secure x86_64 CPUs, maybe some new innovative CPUs with low consumption, maybe memory/solid state drives.


> maybe memory/solid state drives

That's a very low margin and cyclical market since memory/SSDs are basically commodities. I don't think Intel would have any chance surviving in such a market they just have way to much bloat/R&D spending. Which is not a bad thing as long as you can produce better than products than the competition.


Yeah, but they can saturate fabs and provide income, which they need. Intel can't produce better CPU/GPU products than their competition now. Their design and manufacturing of CPUs has serious problems for years now. The big money in GPUs is already captured by NVIDIA, and it's hard to see how Intel can challenge that - people want NVIDIA and CUDA. So Intel should cut down and focus the remaining bloat and R&D spending on the areas where it's plausible they can get competitive in a reasonable time. That is CPUs, and maybe memory and SSDs - they have X-Point which was great, just marketed and priced wrong.


No reviews and when you click on the reseller links in the press announcement they're still selling A750s with no B-Series in sight. Strong paper launch.


The fine article states reviews are still embargoed, and sales start next week.


The mods have thankfully changed this to a Phoronix article instead of the Intel page and the title has been reworked to not include 'launch'.


"old aspirations"

"there is not much money in it"?

WTF?


There is not much money in it for Intel.

Intel tried to get into GPU-like products 14 years ago. They promote their consumer Arc GPUs since 2022, and still almost nobody wants them. Is there a datacenter Intel GPU that some business wants?

The big money is flowing NVIDIA's way, and even if Intel can make a GPU, it won't be able to divert a big part of the flow, similarly to AMD.


If Ryan McBeth defines MIC as just the defense companies, or its existence being conditioned on these companies having greater official revenues than Procter & Gamble, then he either misunderstands the concept, or he is (why?) trying to spread some weak argument for an idea that U.S. does not have an MIC, which is quite comical.

MIC is not just the defense companies, read the name again - it' the complex made of industry and the military. And Eisenhower's point in warning against it is not about revenue of the industry part, but about influence of the whole complex on major decisions.

In 1990's there was a short dip in funding, but since 2000's, its growth caught back on, and it's getting close to a trillion dollars a year. That much money chases a lot of constituency and a lot of power. Millions of people are dependent on it.


To you is it just the industrial complex?


Why would you ask that? MIC = Military Industrial Complex. The complex is made of both the industry and the military.


I ask that because you bring up Procter & Gamble, and imply the same concept exists everywhere, not just military companies.


> you bring up Procter & Gamble,

No, relwin brought it up, and I ridiculed the criterion. I don't get your point at all, sorry.


> There's a certain personality type that is drawn to engineering that believes the whole world can be explained by their simple pet model and that they are smarter than everyone else.

Lots of failed theorists with that personality type/flaw as well.


Yep, after Zen 3-4/Alder Lake, we're now in another stagnation cycle like Intel Sandy Bridge brought in 2010-2015.

For casual users, a good test if it's time to upgrade is - has the CPU speed, the memory speed doubled? If not, for most people, it's better to keep your old device.

For competitive gamers, smaller gains make sense, but it gets expensive fast.


Steve's reviews are focused on gaming and he probably isn't wrong there. 9700X seems to bring very little for gaming, compared to 7700X. 7700X is almost the same performance, sometimes even better, and cheaper to buy. Most gamers do not care about 10% lower power consumption, especially when they have to pay more upfront for it.

Yes, the better energy efficiency allows 9700X to boost higher to get somewhat higher performance in multi-thread, but for some reason, gaming does not benefit noticeably. Zen 5 seems interesting for laptops and low-power client devices, but so does the new Intel Lunar Lake (for now, at least), so we have to wait for reviews and comparisons there.

> has not tested... floating-point computations, cryptography or ML/AI.

That is true, but small fraction of people care about these specialized workloads, it's overhyped in marketing. But if you care about those, I think you may be right that Zen 5 may be more interesting there.


I agree that upgrading from Zen 4 to Zen 5 would make very little sense for a gamer.

However this fact was already well known and it has been discussed for some months.

It was not a surprise and verifying this fact is certainly a stupid justification for calling Zen 5 a flop.

Zen 5 does exactly what it has been announced that it will do. It provides a much greater energy efficiency than any previous x86 CPU.

It has a greater single-thread performance at a given clock frequency than any previous x86 CPU, but Arrow Lake S, which is expected in October or November, will have about the same IPC in the big cores, so about the same single-thread performance.

For any application that can use AVX-512 instructions, the desktop variant of Zen 5, i.e. Granite Ridge, can have a double throughput in comparison with any previous desktop CPU. For some people this will not matter at all, but for others this will be decisive.

The same happened at the previous SIMD throughput doublings that happened while keeping the same number of cores, e.g. Sandy Bridge after Nehalem or Haswell after Sandy Bridge.

For some people this did not matter, while for others it was a great improvement.


It's a flop for people who expect that after 20months, they'll get 13%-18% more. Perhaps Steve did not know this "already well known fact" and thus wrote about flop and Intel 11-th gen vibes.

How did you know before benchmarks were out? Did AMD say gaming performance will stagnate? (that would be very stupid thing for them to say).

In which applications is AVX-512 performance decisive? Video editing / 3D modelling?


There have been a lot of comments on many Internet forums, during the last months, based on various benchmarks of engineering samples, that the gaming performance of these new models will be only marginally better than of the existing Zen 4 models and some times even lower than of those with 3D cache.

Only when the models of Zen 5 with big 3D cache will be launched it is expected that they will be noticeably faster for gaming.

When a 5.5 GHz 9700X matches or exceeds in single thread performance a 6.0 GHz 14900K, that is an almost 10% over the older competition and it certainly is 13%-18% over the corresponding model of the same clock frequency from AMD's previous generation.

There are many professional applications where the AVX-512 performance is decisive. There would have been much more, had Intel not prevented this by their market segmentation policies, which force most software developers to support only the weakest and most obsolete CPUs. I am myself interested in certain CAD/EDA engineering applications, where I expect a good speed-up from a 9950X, at a much lower price than for any previous solutions. This is a nice change at a time when most computing solutions increase in price, instead of decreasing, like in the old days.


> There have been a lot of comments on many Internet forums

Still, the non-improvement in default setting surprised people, e.g. see the embarrasing confession by PCWorld, they did not believe the performance increase is so minuscule and asked AMD if that is for real.

> it certainly is 13%-18% over the corresponding model of the same clock frequency from AMD's previous generation.

More like 10%. And you have to overclock for that. Overclocking has become a fool's errand, you can expect it to cause problems, crashes, etc. Granted, if crashes are rare, gamers may go for it.


> It's a flop for people who expect that after 20months, they'll get 13%-18% more.

If you have unrealistic expectations, everything, everywhere is always going to be a flop.

You're not getting 18% more IPC at 30% energy savings in a single generation. That kind of uplift hasn't been seen probably since Pentium 3 vs Pentium 4 era, or maybe Nehalem vs Core Duo.

Regardless, if you run the Zen 5 CPUs at the same TDPs as the 7000 series, you can still easily get 15-20% uplift. It's just that AMD has chosen conservative defaults for energy efficiency.

And purely for gaming, you should be waiting for X3D versions.


Gamer/enthusiast segment expects performance increase, not energy savings. CPU consumption is not even the greatest power hog in gaming PC.

Zen 3 brought 20% more performance at much better power consumption than Zen 2, and this set expectations. Zen 4 was a weaker improvement, and some people hoped that was one time thing, and maybe Zen 5 will get back to Zen 3 level improvements or better. But the improvement is even worse this time.

That's why in this consumer segment, 9700X is like Intel 11gen, a token increase in performance (and sometimes, decrease) as compared to previous gen, and thus a meh product. In other segments, like in desktops for work, or laptops, focus is different, and the same performance at lower consumption is a great new feature. So it's not all bad - it's just meh for gamers and enthusiasts.

Yes, you can overclock, and expect to either win the lottery, or maybe get problems like Intel has. If AMD did not clock these higher by default, there is a good reason for that, and it is not because of green political reasons. AMD has every incentive to clock as high as possible, to look and sell better. Most probably, the current batches of 4nm chips out of TSMC aren't rock-solid at higher clocks.

Re X3D, yes those should be better. But this is marketed as 9700X, not as 9700, so it's a flop. PCWorld was so surprised by the non-improvement that they postponed their review and checked with AMD if their poor bench results really are what AMD intended them to see.


> Zen 5 does exactly what it has been announced that it will do. It provides a much greater energy efficiency than any previous x86 CPU.

I buy my computers to use them, not to be "efficienr".

I dont' give a shit how much my laptop or desktop uses, but i need power when i use it.


> I buy my computers to use them, not to be "efficienr"

Not every product is meant for you. I bet folk who cool their computers with HVAC and draw power by the MW do care about efficiency a lot.

Also, Zen 5 beats Intel in single thread performance while being efficient (by default). You could always change your bios to get even more perf using more power.
