Suddenly articles like this don’t look so stupid anymore. Why is Intel suddenly so successful in the IGP department after trying (and failing) so hard for so many years?

I haven’t followed the GPU scene for a while, but wow, the 290X seems unbelievable value compared to the Titan. The gap almost seems to be too large to be true.  hardocp review posted:And consider this, for just $100 above the price of one GTX TITAN, you can own two Radeon R9 290X video cards and use those in a CrossFire configuration.

Agreed posted:Here's an article from TweakTown focusing on overclocking and it's about what I expected - low overclocking headroom on the R9 290X (we'll see if that holds or not once non-reference models start showing up and tools allow for more adjustment) From what I read about the new Powertune in the HardOCP review, overclocking this card with the regular reference cooler is completely pointless. The card dissipates up to 300W (three hundred watts) of heat and dynamically adjusts the frequencies to meet a preset power/temperature envelope, which means it actually clocks down to 800 Mhz while running moderately intensive games to stay below 95°C. I wonder how far the GPU would go with water-cooling, probably very high. On a different note, some german sites suggest that the GPU is already somewhat bandwidth-limited at the default 1 Ghz. Or the architecture just scales well with memory bandwidth. http://www.computerbase.de/artikel/grafikkarten/2013/amd-radeon-r9-290x-im-test/15/ https://www.youtube.com/watch?v=PFZ39nQ_k90 eames fucked around with this message at 19:45 on Oct 24, 2013 |

It's pretty pointless because all the games (mostly CPU-bound blizzard games) I play now hover well over 130 fps with all settings maxed and even SSAA in some cases. Should have waited for better (1440p or 144hz) screens or bought a model with the 1060 instead.

I could but buying an external monitor would require a keyboard and extra space on my desk and I bought a laptop to get around that. VR should probably work fine, the Steam VR test gives me a score of 11. I don't have anything to compare it to but it maxed out the scale at "Very High" with 0 frames below 90fps. Perhaps I'll buy a Vive in the future to justify the GPU.

The Lord Bude posted:oh. Oh dear. So what do mac ports of games use? metal? My dream of owning a mac and continuing to play video games is in tatters, although I suppose I could boot into windows. To be honest I can't think of many recent Mac ports. As mentioned above Macs aren't great for gaming unless you build a hackintosh yourself, at which point you may as well dual boot into Windows for the newest games. My 15" rMBP throttles its CPU from 2.3 to 1.3-1.4 Ghz when the dGPU is running at full load for longer than 5 minutes.  That's what happens when you put a 45W TDP CPU and a 50W TDP GPU into a relatively slim case and run the machine off a 85W power supply. They're a bit like like Tesla cars, super impressive for short bursts of speed and the average user doesn't ever use more than that, but it all falls apart as soon as you demand maximum power for longer than a few seconds.  The next rMBP will probably be even thinner and thus even worse for sustained load.

The Lord Bude posted:To be fair I was talking about a 27" imac not a macbook, but I take your point. I was under the impression most AAA games get Mac ports these days. It would still be nice to use OSX most of the time and dual boot into windows for gaming. It's mostly just wishful thinking , given that Nvidia is now putting out slightly underclocked versions of desktop cards for laptops. Or I suppose an external GPU like that thing razer has happening - is that only being supported on that one laptop of theirs? The iMacs are of course better for gaming but their GPUs are still abysmal compared to the native screen resolutions and what's available on the market. A new iMac with a mobile GTX1080 is technically possible and would play most games at half resolution with decent frame rates. All we can do is wait and hope.  External GPUs already work with Macbooks. Check the techinferno forums for more info. Compared to an internal card you can expect ~25% lower framerates using an external monitor and 40% lower frame rates using the internal laptop monitor because of TB protocol overhead. I posted about this here. The Razer core housing costs $500 and a GTX1070 costs $450, so you're probably better off building a separate gaming PC for the same price. You may even be able to buy stripped down GTX1060 laptops around that price in the future.

FaustianQ posted:I'm wondering now if it's not just a complete 28nm product, basically Polaris XT on 28nm? That's a ridiculous die size but it might explain the TDP? If that is true (and I think it is) then Sony was probably caught with their pants down when Microsoft announced their next Xbox. The PS4 Pro looks rather lacklustre in my eyes. It seems like they primarily built it for the PSVR and they threw in a questionable non-native solution for 4K as an afterthought to keep the marketing department happy. I suspect we'll see a PS4 Pro slim shortly after the new Xbox is out. 310W...

SwissArmyDruid posted:Ho poo poo, I thought the 455 thing was scuttlebutt, and not that there was an actual product.  If that's true the base 450 really won't be noticeably faster than the iGPU? I assume it was cheaper for Apple to drop that trash chip in than design a separate iGPU only 15" model with custom PCB layout, heatsinks, etc. Particularly because it would have been a dead end because GT4 KL is nowhere in sight. The 460 is ok I guess, assuming 35W it is at least in the same TFLOPS/watt ballpark as a GTX1060.

This new AMD site confirms the Polaris 11 specs. 1/1.3/1.86 TFLOPS. http://creators.radeon.com/radeon-pro/ quote:The Radeon Pro Graphics processor found on the MacBook Pro is thinner than a US penny with a Z-height of only 1.5 mm. Aww yes, package height is the first thing I'm looking for when I go out to shop for a GPU.  Twerk from Home posted:The base 450 is going to be a lot faster than the iGPU, because the new 15" has a weaker iGPU than the new 13". They didn't spring for the big Iris GPU in the 15" guy this time around, way to go Apple. The point still stands, Skylake GT4 iGPU would have been on par or faster than the 450. Rolling out their laptops with Iris Pro would have forced them to a.) design a 15" iGPU-only SKU or b.) sell a laptop with a dGPU that's slower than the iGPU as Polaris yields are probably not good enough to put 455/460s into every MBP.

That power consumption decrease seemed impressive until I read the slides. slides posted:In World of Warcraft on an 8GB Radeon RX 480, Radeon Chill did the following: and then in a sentence two paragrpahs down: quote:"Here’s one example taken from World of Warcraft. In this case, the FPS average is measurably higher with Radeon Chill turned off—125 FPS versus 62 FPS with Radeon Chill enabled."  They're basically throttling framerates depending on movement on the screen. I guess this will be useful for laptops but I don't think it'll do much if anything with a RX 480 and a 100hz 1440p screen.

I'd expect HBM to have far lower latency though, surely that has to affect performance as well. As for AMD stock, I think there is a good chance that Ryzen/Vega will be a disappointment compared to Kaby Lake/Pascal. The APUs should be very strong though, I'd say it is almost certain that AMD has the next console generation locked down. Musk said that the decision between NVIDIA and AMD for the new AP hardware was very close, so they are must be doing something right there as well. Add the fact that Intel and NVIDIA want AMD to stick around for antitrust reasons and I'd say things are looking pretty decent. I don't own AMD stock but I wish I did.

I'm not sure how accurate the "Interface Load" HW monitoring is but I'm seeing 5-6% bus load streaming games at 2880x1800. That's 40% more pixels than 1440p using a 1060 and PCI-e 3.0 x16. The load is even lower (2%) with software encoding because the CPU can't keep up.

I am trying to play Rise of the Tomb Raider at 2880x1800 (roughly equivalent to UW1440p) with the High Preset except for Textures set to Very High on my 1060-6GB. It looks great. Framerates (~40 FPS) are acceptable to me because I'm using it for steam in home streaming. The only problem is that the game keeps crashing with a message that it ran out of RAM. My OSD sometimes shows frame buffer usage up to 5.8GB. Is 6GB really not enough at this resolution?

craig588 posted:Are you using DX11 or DX12 mode? When I played it back on launch DX12 was notably less stable for me and didn't appear to have any dramatic image quality improvements. DX11 for the same reasons you mentioned. DX12 also seems to double the steam streaming latency. EdEddnEddy posted:RAM is your local memory so either it has some sort of memory leak and its eating up your full Ram amount + swap file, or your swap file is off and you still don't have enough ram for all it's trying to load and use at the time. Swap file is on & automatic, it's running in a VM and I had 8GB assigned to it. I bumped it up to 12GB RAM and the crashes stopped. Looks like the "Very High" texture setting really does use more than the 6GB VRAM of my card and starts swapping into RAM (failing that perhaps even swapping textures onto the SSD). I've set textures to "high" now and things have settled at ~4GB VRAM usage. Note to self: Buy 8GB+ card next generation

Surely a Pascal refresh would be a much more likely response than early Volta? A few percent more cores here, a bit higher clockspeed there and perhaps even a bump in memory bus width... job done?

titanium posted:The self boosting really confuses me, so what's the point of setting +200 if it's going to hit 2000mhz even if its only set to +39? Pascal automatically adjusts core frequency up to a certain maximum temperature, maximum voltage or maximum power consumption cap . Setting an offset of +200 means that it clocks higher relative to the voltage. i.e. if it would normally "boost" to 1800 Mhz at 0.950V and 1836 at 0.975V, it'll now boost to 2000 Mhz at 0.950V and 2036 Mhz at 0.975V, obviously at the potential cost of stability. (those are random numbers I just made up) Since lower voltage results in lower power consumption, the card will reach higher clockspeeds until it either reaches the maximum voltage or the total cap of 180W.

I use Precision X mainly because my card is from EVGA and I haven't tried anything else. Things that continue working after the app is closed: adjusted temp/power target raised voltage limit frequency offsets and custom frequency curves doesn't work after the app is closed: custom fan speed curve (seems to either get stuck at fixed percentage or reset to the default bios curve, the former can be kind of hairy although the you will throttle before anything terrible happens)

FWIW RX480s are on sale with significant price cuts, so perhaps we'll really see a Polaris refresh soon. The "MSI RX480 8GB Armor OC" is on sale for $172 after promo & rebate, reference cards for $180. If only AMD would support steam streaming hardware acceleration, I paid 290€ for my 1060-6GB only two weeks ago.

Heise.de claims the 570 and 580 are coming on April 4th, 560 and 570 a week later. All of them are Polaris refreshes/rebrands. Vega around Computex in May/June. They're usually very reliable and don't publish rumours unless they have an inside source. https://www.heise.de/newsticker/mel...il-3637882.html The leaked RX 580 benchmarks suggest 1070 performance, if they can delvier that around $300 it'll be quite solid. We'll find out more in a few hours.

There are some rumours about a 1060 Ti making the rounds now but nothing substantial. If true that would make a Pascal refresh rather unlikely; Nvidia probably feels like they can deal with Polaris refresh with one new card between the 1060 and 1070 plus the odd price drop here and there. I think it's going to be 1080 Ti launch now, RX5x0 Polaris refresh in April, Vega with 1080 performance in June and then nothing until Volta in Q1 2018. Vega doesn't look like it will be competitive at the top end but the Zen + Vega APUs should be very, very interesting.
