Intel Teases 6 GHz Raptor Lake at Stock, 8 GHz Overclocking World Record (tomshardware.com) 55

Tom's Hardware reports: We're here in Israel for Intel's Technology Tour 2022, where the company is sharing new information about its latest products, much of it under embargo until a later date. However, the company did share a slide touting that Raptor Lake is capable of operating at 6GHz at stock settings and that it has set a world overclocking record at 8GHz - obviously with liquid nitrogen (here's our deep dive on the 13th-Gen Intel processors). Intel also shared impressive performance projections for single- and multi-thread performance.

Notably, the peak of 6 GHz is 300 MHz faster than the 5.7 GHz for AMD's Ryzen 7000 processors, but Intel hasn't announced which product will hit that peak speed. We also aren't sure if a 6GHz chip will arrive with the first wave of chips or be a special edition 'KS' model. Intel also claimed that Raptor Lake will have a 15% gain in single-threaded performance and a 41% gain in multi-threaded, as measured by SPECintrate_2017 and compared to Alder Lake, and an overall '40% performance scaling.'

    Let me know when they start shipping silicon of this speed in large quantities. Most folks don't have liquid N2 setups to do this sort of overclocking, either, so that point's a bit moot. Intel's also still a lousy investment financially, which doesn't say much for its future technologically. Maybe the CHIPS act can bail them out, but I don't think it's going to provide enough money to do much. My.Magic Eight Ball says "Outlook not so good" which seems about right to me.

      CHIPS barely moves the needle on Intel's ready cash, they've got liquidable investments far exceeding the amount of our money Congress is handing them to do what they should be doing anyway. They could burn cash at their current rate for years without running out.

    • I do no see the CHIPs act bailing them out as Intel's problems the last few years was not about finances. Their problem was engineering due to low yields at 10nm for 5 years. It looks like they have finally solved their issues at that feature size. Their progress extending to their 7nm remains to be seen.

      Generating $0.8bn cash last quarter, paying out a $1.5bn dividend, and changing their end-year forecast from $65bn revenue to $68bn is "outlook not so good"?

    Just days after writing about how hot the future Ryzens will be at speed ... with not a mention of heat from the Intel part.

    A deja-vu even, the 12900K needed almost double the power to compete with the 5950X with hardly a mention of how hot the Intel ran then either.

      The competition is good for the industry. Let them keep leapfrogging each other.

      Personally, I haven't felt the need to upgrade in years. I'll take my 64GB of RAM and 32 threads and won't care if it's bleeding edge. Plenty fast for anything I'd ever throw at it.

      At work, we've been bouncing Intel in favor of AMD Epyc for a few years. It's been a much better deal in terms of cost and cost per watt....at least for our typical workloads. I'm sure there are companies out there that will pay a premium to eeek out that very last FLOP....but not me.

      Best,

        For me, I bought AMD mainly because of their promise to use the same socket for a certain number of years. I was able to upgrade to a newer chip for better performance. I only got a new and better board when it was on sale but I would have been fine on the same board otherwise. With Intel, it seemed like I had to buy a new board and CPU every two years to get more performance.
        • So you loved the idea of easy upgrading but in reality that didn't matter? How does this argue for AMD?

          • Did you miss the part where I did upgraded the CPU more than 2 years later? Or the part where I got a newer motherboard and used my current CPU. If it had been Intel, either upgrade would have not have been possible with other hardware upgrades.

        That's because most problems are RAM- or I/O-bound, not CPU-bound.

        When the CPU has to go to RAM it's 100s of clock cycles. For a single-threaded application (i.e. most of them) and a cache hit rate of 99% that still means 99 clock cycles executing instructions then 100-300 clock cycles stalled fetching memory to fill the cache miss. I/O latency to something as fast as SSD is even longer.

        What's it called when one of the frogs just keeps leaping over itself?

    • Maybe like everyone else, I assume 13th Gen Intel will be hotter and use more power based on history.
    • by AmiMoJo ( 196126 )

      In addition, the clock speed a CPU is capable of is irrelevant for most people because the limiting factors are heat and power.

      I.e. having a cooling system capable of removing enough heat, and having a power system capable of delivering enough juice.

      I don't know why Intel bothers with stunts like this. Does anyone buying CPUs not check independent benchmarks on more realistic systems?

      • Also it remains to be seen if increasing clock speed increases performance linearly. There might be limiting factors on the chip that there is less performance above a threshold. While Intel might be able to run at 8GHz it only gains a few percentage points in performance while requiring a lot more power due to bottlenecks.

            Well there is the transistor aging. Good for at least 10 years worst case when *operated within the specified frequency, voltage, temperature envelope*.
            We could make them clock faster if you were happy with a fraction of the devices bricking after 2 years.

            The circuits I work on won't actually work down at super low temperatures. The thermal noise is not noisy enough. We design for and test down to -40C, but who knows what's happening below that? Nothing good I suspect.

          • It's not nearly that simple.

            AMD has been less austere with its cache- which is fantastic, but memory architecture-wise, Intel is on top. Their latencies have been and continue to be better than AMD parts.
            For a while, you could run faster memory on AMD parts, but then Intel leapfrogged with DDR5, and really, that's not about memory architecture anyway.
            • by gweihir ( 88907 )

              Nonsense. Do you remember how long it took Intel to integrate the memory controller in the CPU? That was years after AMD because they could not do it. Also, latency is by far not everything. Also notice how Intel is now planning multi-chip modules, again years after AMD and after they stated they would never do that. Intel is playing a game of catch-up and they are not winning.

                Not relevant to the claim. Why the strawman?

                Also, latency is by far not everything.

                Eh, it really kind of is.
                There's bandwidth and latency. Other than that, both consumer grade chips are quad channel. And Intel still outperforms in both metrics.

                Also notice how Intel is now planning multi-chip modules, again years after AMD and after they stated they would never do that.

                What the fuck does this have to do with the qualitative analysis between UC memory controllers?

                No, you're talking out your ass to to grind an ax.

        • Also it remains to be seen if increasing clock speed increases performance linearly.

          I'm sure cache misses prevent linear improvement. For example, if you run at twice normal speed then you're going to hit main memory twice as frequently. For benchmarks that keep everything on processor caches that are tied to the CPU clock this will not matter. More serious programs will need to hit main memory and this will prevent linear scaling with a faster clock.

        the clock speed a CPU is capable of is irrelevant for most people because the limiting factors are heat and power.

        It's also getting limited by the speed of light, or for silicon, the speed of electronic signals through silicon that's about 2/3 the speed of light (with variation depending on what's going on in the silicon).

        For understanding, 6 GHz frequency means 0.166 ns, so light travels about 4.79 centimeters, electric signals travel about 2.9 centimeters during that time. The electric signal bouncing all around the circuitry of the chip needs to flip all the transistor switches by traveling less than 3 centimeters.

        The 8 GHz frequency means 0.125 ns, light travels 3.75 centimeters, electric signals travel about 2.25 centimeters.

        For some of the winding circuitous paths around the chip and the large numbers of transistors that need to be hit, at these frequencies one clock tick's electric pulse can still be spreading around the chip when the next clock tick is triggered. One tick happens before the electric signal can travel the distance of the chip. So not just heat and power, but also the distance that must be traveled around the chip.

        • Clock propagation has been a known issue in semiconductor at least since the late 90's when I was studying semiconductor design (yeah I'm date myself). I really should see what techniques that they've come up with since then. Back then they were saying we were reaching the end of Moores Law due to feature size, but they kept kept finding new ways to decrease feature size that previously was thought of as "not possible" due to physics.... and today we've got EUV, and phase-shift pattern masks coming.

          So not

          Which is perfectly OK.
          As long as some other part of the chip cannot engage in superluminal communication, signal causality is preserved.

    • Winters DO get cold where I live. It will be nice to have a warm PC under my desk....

  • While the numbers look impressive, there are some details not disclosed like how many and which processors are capable of 6GHz. As noted, the article questions whether the high speeds are only achievable with the fastest KS variants. The other not disclosed is the power requirements. Yes the Intel flagship 12900K currently beats AMD's flagship 5950X but it requires way more power to do so in some benchmarks. As with AMD's 7000 series, we will have to wait until people can verify both companies' claims.
  • "AMD went to 5GHz?! Well, fuck it. We are going to 8 GHz [theonion.com]."
  • Buy AMD, get more, pay less. Also, Intel has a history to lie with these benchmarks and to demonstrated "products" that you later cannot buy or buy only after along wait and in very small numbers.

    • That hasn't been true since they jacked up the $199 6 core (3600) to launch a $299 6 core (5600X). They found themselves on top of gaming benchmarks and decided to gouge consumers. Now you can buy a 10 core 12600K for the low 200's vs the 5600X which has fallen only to the low 200's.

    Almost all of the security issues are caused by speculative execution in the name of speed. In today's work of cloud computing, please just focus on making the processors more secure.
    • SpecEx is also the mechanism that enables CPUs to actually get work done at GHz speed instead of Pentium speed. So SpecEx could be disabled but then your AWS jobs would take 10x as long and cost 10+x as much. Security is mostly a question of economics, anyway; your beancounters and lawyers can explain how that works to you.

    I mean, I like fast computers, don't get me wrong... but how many people actually have a good use for a 100W+ desktop CPU these days? Especially as GPUs are the dominant need for modern gaming, is a 6-8Ghz CPU actually all that valuable? No doubt next gen gaming engines are going to be even more GPU dependant and less CPU dependant.

    Meanwhile (puts on flame suit) Apple is putting out competative chips at a fraction the power draw and qualcomm is eyeing that same market.

    I just feel that making more performance/W is the better route for 99% of consumers. Obviously the gaming industry isn't jumping over each other to get on Apple silicon, but I think it is actually an interesting platform for them considering commonalities with the booming mobile gaming industry. If Qualcomm puts out something in the ballpark of Apple but 'open' so to speak, that could be a very interesting direction.

    Intel seems to just be trying to pour on the brute force. I admit gen12 performace+efficiency cores contradicts that a bit, but really they are trying to hold onto the idea that you need a big fat CPU in an era where GPUs are dominant and modern software is more and more multi-threaded. AMD seems a little more keen on this than intel..

  • no mention of the power consumption of these things...

  • If you build a gaming PC based on Intel and any of the new gen GPUs, you will be very close to exceeding the power limit of a standard US wall outlet. You already cannot have 2 gaming PCs in a single room if the room is only one circuit. This is the wrong direction. I don't want to hear nonsense about clock speeds - I only care about MIPS/watt.
