A lot of engines put subroutines like resource allocation, networking, and a bunch of other things in separate threads - which does help some. Multithreading is still insanely hard to get right, even with threading sanitizers like in LLVM - assuming game developers use tools like that.

Some Goon posted:Notably, Cyberpunk. The kind of multithreading I'm talking about is taking something that normally runs on one thread and parallelizing it; ie. how video encoding and decoding used to be thought impossible to do single-threaded, but it turns out that assumption is wrong, which is why you don't need a 6GHz CPU to handle h265 in software.

BlankSystemDaemon posted:I haven't had time to examine it with dtrace, but from what little I've seen I get the impression that it's doing what other games do, ie. separating things in their own threads - which does make use of multiple threads on an SMP system, but a sufficiently fast UP system can make up for it. You'll never get that kind of parallelization since games are linear with respect to time, whereas you can encode or decode multiple sections of a video file at once. Games are going to be constrained by the speed of the thread their main loop is running in, but games that are designed for it will expect there to be multiple threads to process things in parallel on and will get bogged down if you try to cram 6x the work into the one thread, it's not something you're going to cover with clockspeed alone. At launch Cyberpunk poo poo the bed when running on a processor without enough threads; fast 4C/4T CPUs have been showing this weakness for years now, Cyberpunk takes it to the next level.

The framing of “single-thread only matters if games use literally one single thread” is false. Virtually all games are single-thread bound even when they use multiple threads. (In fact, given sufficient threads, all multi-threaded programs are single-thread bound, that’s what Amdahl’s law says.) (The more correct phrasing is per-thread performance, not single-thread performance, which isn’t strictly the same thing but 99.9% of the time “performance per thread at all core load” is what someone means by single-threaded performance , not actual 1T performance. In the case of true 1T performance, that hasn’t mattered for a long time, like a decade now.) There’s no reason to beat around the bush or add qualifiers, Rocket Lake will be the fastest gaming CPU on DDR4, period. And titles where it does win will be more about Zen3’s giant cache than thread count. To some extent that doesn’t matter, because your real framerate in games is “min(CPU_FPS,GPU_FPS)” so in many situations if you’re playing at ultra settings you’re going to be GPU-bottlenecked. But that’s a completely separate issue from “rocket lake will only win in single-threaded games”, which is false. On the other hand there are titles where CPU performance actually does matter, BF:V for instance was very hard to get to a locked 144 FPS, Zen2 was single-thread bound/bottlenecked in the 115 FPS range - despite the game happily using 6+ cores. And it’s a title where you don’t just open-palm slam everything to ultra settings, it’s a competitive title and you want to maintain a high framerate, despite it being very CPU-intensive. It's not uncommon to run medium settings there. COD probably is another example where you don't just run max-everything. As far as Rocket Lake more generally: I doubt that Intel is going to budge from their traditional set-points on the pricing tiers for i3, i5, i7, etc. The i9 is going to be kind of a “y tho” SKU because the only thing it brings you over the i7 is Thermal Velocity Boost when that only matters under specific narrow circumstances (CPU is under 70C) and you could just manually overclock anyway for better results. So the i7 is likely to be a very good 5600X/5800X competitor - for an extra $25 over the 5600X you get 2 more cores (more future proof) and faster gaming performance, and it will outperform the 5800X at $75 cheaper. The downside will of course be that it’s more difficult to cool and will require a more expensive motherboard. Under non-stress test conditions the disadvantage isn’t going to be all that bad, but they simply won’t be as efficient as AMD’s 7nm processors. The motherboards wind up being maybe $50 more expensive than AMD to account for better VRMs/etc (the sub-$100 tier of AMD motherboards are bad and shouldn’t be used as a comparison for a high-end rig), and the cooler is a wash nowadays since AMD is done with giving you a decent free box cooler (5600X is now the lovely low profile cooler that doesn’t work well, box coolers are removed from all other SKUs). (And I’m going to note right upfront that Prime95-based stress tests for power/thermals are going to be lol at gaming clocks because of the AVX-512. Gaming is way, way less intensive than Prime95 in general but that delta is getting wider and wider as the AVX cores get wider and wider. Intel has AVX offsets configured to keep this under control but people insist on turning them off and that’s going to be lol with gaming clocks and doubled/quadrupled AVX units.) So basically net-effect it does carve out a bit of the price advantage but it’s still likely that AMD is going to come out a little more expensive for a slower (but more efficient) product. It is quite probable that AMD will be forced to lower prices (or release the 5600 / 5700X SKUs) in response. We’ll see how low they are willing to go with everything insta-selling out anyway, but they’ll probably launch something to help steal Intel’s thunder a bit, I think. The biggest problems with Rocket Lake isn’t really the numbers though, it’s the intangibles. This should have been launched <6 months after Zen2 to keep the performance edge. I realize it’s ready when it’s ready and that backporting takes time, but Ice Lake launched in that timeframe and this is essentially 14nm Ice Lake (it’s technically Tiger Lake minus the cache changes - but cache changes were the major change from Ice to Tiger Lake). If they had launched back then they could have held a 30% lead over AMD gaming performance and that would have been a marketing story that they could work with. Instead, they are launching 6 months after AMD leapfrogged them, and only leapfrogging it back by a small amount, with a more power-hungry processor. On top of that it’s only i7 and i9 that are getting Rocket Lake. Lower SKUs are going to be Comet Lake refreshes. So no PCIe4, no NVMe lanes, slower gaming performance, etc. The i7 is basically the only SKU to care about imo. And in general the processors are all fast enough nowadays. Rocket Lake is only like 8% faster than Zen3 which is only like 8% faster than the 14++ Lakes. This isn’t 14++ Lakes vs Zen1 anymore, it’s kinda this-that-or-the-other as far as buying a gaming processor. Availability and relative pricing is kinda gonna determine which you get. If AMD can get a 5600/5700X and keep it on shelves that’s fine, if intel can keep this on shelves that’s fine too. I don't think either Rocket Lake or Zen3 are worth having waited 3 years from the 8700K launch, for basically 15% improvement in gaming at iso-price. The best move still remains having shut up and paid Intel the asking price for the 8700K and just riding it until second-gen DDR5. I waited for the 9900K and I think even that was a mixed bag considering the bump to the $475 price point and the extra year it took. If you are doing heavy productivity work regularly then AMD probably remains the best game in town. The margin may be eroded a bit by AVX-512, tasks like Blender and x265 do benefit from it, but probably not to the extent that the 11700K beats the 5900X. It may shift the math on the 5600X/5800X or 3900X though. That said, that’s really not a lot of consumers compared to gaming. Paul MaudDib fucked around with this message at 00:10 on Dec 29, 2020 |

That's not my fault, I couldn't convince MS and Sony to do that even I wanted to. I'm sure there will be some titles that have a design that massively benefits from more cores. There are one or two out there right now that benchmark significantly better on 12/16c. But it won't be most games, and it's especially not the type of game people tend to chase 240 fps minimums in. Although with consoles getting far more powerful CPUs and desktops getting beefier as well we might see some grander scale game designs come into existence this decade. I have a 3900x and have had no issues with it. Prior to that I had a 3770k which is still a good gaming CPU (~35% slower than zen3/modern Intel CPUs in games that run identical on 4c to 6c/8c). I've no loyalty or aversion to either company when it comes to cpus. Intel and AMD are both great choices right now so buy the one that has a cheaper motherboard+CPU combo at the feature+performance level you need. Availability may also be a deciding factor for people who want an immediate upgrade. Khorne fucked around with this message at 05:48 on Dec 29, 2020 |

Intel doesn't really change their price points, they change what they offer at a given price point. we already know the i7 is 8C16T from leaks, I don't see Intel changing their i7 price point, it'll be $375-385 RCP+tray price just like the last fifty-seven generations have been. that essentially guarantees that it will come in under the 5800X (which is $449 MSRP). AMD will probably launch the 5700X shortly before Intel launches in order to stay competitive, but Intel basically can't not come in under AMD's current pricing unless something drastically changes.

it's always a little funny to see the AMD fanboys assume that Intel is just going to come in above AMD at every price point with something inferior. Intel does respond when AMD is perceived as ahead, in response to the 1800X intel launched the 8700K which basically dumpstered the 1800X in gaming and tied it in productivity at 2/3rds the price. In response to Zen2 (and up to 16 cores it offered), Intel cut the prices of the X299 processors literally in half and hit price points that AMD didn't with TRX40 (and consumer boards don't really substitute for the memory/IO capability of HEDT). Obviously there is only so much they can do with the silicon they have, you can't magic products out of thin air, but they do respond when they are getting legitimately beaten in a serious way (which, AMD fanboys pretty much have been nonstop shouting they're beating Intel for the last 10 years even when it's not the case). This generation Intel is allowing memory overclocking on B560, which cuts the cost premium that Z-series boards imposed (particularly relevant for midrange builds), and the i7 is basically going to be the i9 minus 100 mhz, while coming in $75 cheaper than AMD's 8-core. The 6-core is going to be probably $75 cheaper than the 5600X as well. Both of them will be faster in gaming, and completely matching it in IO capability. That's really not an overall bad deal for a gaming-focused home user. Still nothing in the 12-core class, which is a bit of a bummer, but those only really come into play in productivity tasks at this point. AMD pretty much is going to have to respond with the value-oriented SKUs they didn't want to launch this year. So either way you benefit. AMD's availability hasn't been as good as Intel this year (oh how the turntables) though so regardless of what they do on paper, good luck actually buying it.

Not Wolverine posted:Hold on, what did I say? Lets take a closer look: Yeah but still what exactly is your point here. That games will become increasingly parallelized because consoles are now 8c/16t parts? Sure. But then you said that you can't think of a use for the 11700k except for running a 5950x bot. Does that also mean a 5800x has no use for gamers? Do you think that by the time the per-thread performance of the 11700k cannot run a game at xyz level, that a 5950x will be doing much, if any better? The performance per-thread is going to limit you in gaming long before core count does. There is going to be no game where a 5800x can't run it, but a 5950x can. Even by the time games are that efficiently parallelized, the 5950x will be an outdated cpu in per-thread performance. That will be your limiting factor. In some not-perfectly-parallelized apps (but still better than gaming is currently and possibly for a long time), the IPC and clock improvements allowed an 8c/16t part (5800x) to surpass a 12c/24t (3900xt) part from last generation. Why do you think a 16c/32t part from this generation will somehow outlast an 8c16t part in gaming, of all things? If for gaming strictly the 5800x and 11700k are "turds", then the 5950x is just a more expensive turd. Like if you wanted to make this about what is surely to be comical power consumption of the 11700k, fine.

The 11700k will be the best gaming cpu until amd/intel release ddr5 based chips. If they price it aggressively against the 5800x it will be a very good buy if you aren't doing sff and can throw cooling at it, but gaming power consumption honestly won't be that much worse than zen3. 20w probably. The consoles are going from 8c8t to 8c16t but the much bigger impact in cpu performance is the massive uplift in per core performance going from cat cores to zen2. If anything there is less incentive with next gen consoles for game devs to spend resources wringing as much performance as they can from parallelism because they aren't hamstrung by an absolute garbage uarch. Suggesting a 16c32t CPU for gaming is uhh... Silly. And that's being charitable.
