AMD teases Radeon RX 470 performance and Polaris 11 details

A few days ago at the PC Gaming Show event during E3, AMD CEO Lisa Su revealed the RX 460 and RX 470 graphics cards for the first time. The days of seemingly-endless Pitcairn rebrands are over: these cards, along with the RX 480 that was already revealed at Computex, will all be based on AMD's new Polaris graphics architecture. This is good news for AMD and for the market, and today we have some information on these cards courtesy of a deck of slides from AMD.

The slide above confirms most of what we already knew or suspected about Polaris 10: 36 GCN compute units and a 256-bit memory interface. Those 36 CUs translate to 2,304 shader processors, putting Polaris 10 squarely between the Radeon R9 380x and R9 390 in terms of shader count. The specs match entirely with what we know about the Radeon RX 480.

However, buried in those same slides is some benchmark data justifying the "2.8x perf/watt" claim. AMD claims to have tested a 110-watt RX 470 versus a 180-watt R9 270X to come up with that figure. The little 110-watt GPU scores an impressive 9090 in 3DMark Fire Strike 1080p, and manages an average 46 FPS in Ashes of the Singularity (1080p High preset), a 60-FPS average in Hitman (1080p High), and 121 FPS in Overwatch (1080p Max). Based on that kind of performance, we feel comfortable saying the RX 470 is based on some permutation of the Polaris 10 chip in the RX 480.

The RX 460, then, is likely based on the smaller Polaris 11 chip that until now was just a big question mark. AMD said in the past that Polaris 11 would not require an additional power connector, and indeed the board that Lisa Su showed at E3 lacked one. As it happens, Polaris 11 is a much smaller chip than its big brother, with only 16 CUs and half the memory interface width. Lest you become discouraged, remember that the GeForce GTX 960 also wields a 128-bit memory interface. Some back-of-the-envelope math based on the 2 TFLOPs performance AMD is touting suggests a clock rate around 1GHz for this chip.

AMD is making that same 2.8x performance-per-watt claim about Polaris 11, and there's benchmark data for it, too. Instead of the RX 460 that Ms. Su showed off, however, the company tested an "RX 480M," the first mention we've seen of that chip. The company says the RX 480M with 16 CUs is a 35W part that scores 7200 in 3DMark 11 and 4070 in 3DMark Fire Strike. This was compared to a Bonaire-based 82-watt R9 M280X with 14 CUs that scored 5700 and 3500 in those same tests.

These performance comparisons have little context and come straight from AMD, so they are best taken with a handful of salt. Still, taken at face value, the numbers are impressive. The 46 FPS average in Ashes of the Singularity puts the RX 470 squarely in R9 390 and GTX 970 territory, although some of that is likely the result of driver improvements since our test. Depending on the gap between the 470 and the 480, Polaris could be quite the coup for AMD. We'll see on the 27th.

    So exciting. No more re brands. I can finally recommend AMD cards to my less tech savvy friends!

      No more rebrands? You mean, finally, AMD is introducing a new GPU architecture with Polaris. But next year we don’t know if AMD will do rebrands of this year’s Polaris chips again.

    Polaris 11 probably isn’t very interesting unless you’re on a tight budget or you value TDP over anything else or just play find-the-missing-items games. Polaris 10 at $200 for 4GB should make a clean sweep though, if it’s all it’s cracked up to be. I’ll probably end up with a cut down Polaris 10 (RX 470?) with something like 2,048 SPs enabled at maybe $150. Still, $200 isn’t so bad, and I see many people forking over the extra 50 bucks for 256 more Stream Processors (I love how they coined that term… makes these specs sound so… er..). Of course, different strokes for different folks.

      Strongly disagree; Polaris 11 is the most exciting laptop chip in absolutely ages.

      Even if it doesn’t match mobile Pascal, it will bring some sorely-needed competition to the Optimus-dominated laptop market.

      Without that Competition, Optimus laptops have gone unchallenged at silly price points for several years. Do you really think that a GTX 960M adds $300 value to a laptop when it’s just a rebadged $99 750Ti? Want a GTX970M? That’ll be $500 please, for a rebadged and clock-hobbled GTX960 worth less than the $149 you can get those for.

        Without vastly improved software on amds side, nothing will change. Im with you on the need for competition, but they need more than improved hardware.

          What’s wrong with AMD’s software? I say this as someone that owns an inexpensive Lenovo with AMD M275X switching graphics… it pretty much just works. And I can install the latest drivers directly from AMD, no waiting for the manufacturer to bless them.

            • sweatshopking
            • 3 years ago

            It is far behind optimus in almost every regard. It is better, but still far behind.

            • tipoo
            • 3 years ago

            Name some regards?
            I hear this a lot, I’ve used a lot of GPUs, and both AMDs and Nvidias drivers work 95% of the time and poop the bed 5% of the time, I’ve not experienced much difference in terms of bed pooping.

            • NoOne ButMe
            • 3 years ago

            The most recent I have known is that switching was janky and needed programs closed and done manually. But this is very old and my memory. Which is bad at best times.

            My only question is if AMD’s graphics switch has the dGPU connected directly to the outputs instead of like optimus where all but a few machines have the output from the iGPU.

            • Pitabred
            • 3 years ago

            I’m pretty sure it runs through the iGPU’s output connections, otherwise the default of using the iGPU wouldn’t work. The dGPU just takes over rendering when it’s configured to.

            • NoOne ButMe
            • 3 years ago

            There are a few optimus laptops I believe made by ASUS where the iGPU can be fully disabled and the dGPU still can output directly.

        Was referring to the desktop Polaris 11 in the hands of Lisa there.

          Heh, I’ve never heard someone calling their opinion a mistake before.

          People are entitled to change their opinions when given more information that they either didn’t know before or hadn’t considered, but at any point in time an opinion is just an opinion and mine is no more or less valid than yours until real facts come along to substantiate things 😉

            • ronch
            • 3 years ago

            I was a little confused when you mentioned Polaris 11 was gonna be the most interesting laptop chip. I have always held the view that it’s a desktop part but didn’t think it would find itself in mobile. So when you mentioned mobile, I had to agree for a while and ‘admit’ my mistake, which I took back (edit) when I found my footing and remembered that Lisa was holding a desktop P11.

          • ImSpartacus
          • 3 years ago

          Even on desktop, Polaris 11 is still very important.

          There’s a massive chunk of the market that buys off-the-shelf desktops and they are glad to have a spare pcie slot. They need a gpu that doesn’t require any external power connectors.

          Nvidia has owned that market with the 750 ti and, recently, the 950. Amd isn’t even close with their current stuff.

          As seen in their ces demo earlier this year, Polaris 11 eats the 950 for breakfast. It legitimately brings console-tier performance to the <75W graphics card market.

          I know it’s not sexy, but it’s a really big deal.

          For context, the 480’s 150W tdp was also carefully chosen because it only needs a single 6 pin power connector. Lots of older PSUs only have one 6 pin power connector, so this is another critical market.

          I’m amazed that no one is talking about this. Polaris isn’t flashy, but it’s strategic as fuck.

            • ronch
            • 3 years ago

            Oh yes. Polaris 11 will no doubt be important in mobile. But I am mainly interested in desktop gaming, so I probably will go straight to P10 especially since they’re not really that expensive.

        • tipoo
        • 3 years ago

        Absolutely. And bear in mind the >2Tflops has significant meaning in that non-chunky-dedicated-gaming laptops will outpower the PS4, which will likely mean they’ll comfortably run games at “just above console” settings for the rest of the gen, even with the console iterations coming out.

      • Zizy
      • 3 years ago

      Judging by TF numbers, the part is about 15% slower (5 vs 5.8TF). And from leaks, bandwidth reduction is similar as well. So, performance should be about 15% lower (stock vs stock)
      So hum, about 20% lower price (160 vs 200) for about 15% less performance. Sounds reasonable to pick either in terms of perf/$. Depends which is closer to the price or performance target.
      If 470 will also have 8GB version for 200$, the same as 4GB 480, I wonder which of these 2 will be more popular.

    • Bensam123

    And it will probably launch before normal people can actually buy a 1080 or 1070… Nvidia has definitely bungled their launch, lets see what AMD does with theirs.

      • f0d
      • 3 years ago

      there are plenty of people with 1080’s and 1070’s already, a friend of mine on a different forum already has a non-FE 1070 and as of writing this there is a non-FE 1070 available here
      [url<]https://www.pccasegear.com/category/193_1829/graphics-cards/geforce-gtx-1070[/url<] they seem to be going in and out of stock daily, if you want one you can get one with some shopping around

        • Pitabred
        • 3 years ago

        “Plenty” is relative. It was only a hard launch in spirit, it’s still nearly impossible to get hold of one. There wouldn’t be listings for $1000+ on eBay and Amazon if they actually had enough supply for the launch.

        • Bensam123
        • 3 years ago

        Yup, I’m watching a aggregator for sales and they’re ‘in stock daily’… all 10 of them, and sell out within 1-3 minutes.

            I had a friend of mine who moved to the US send me a Radeon 9800 Pro when the exchange rate was so high it made sense to do so ($2 to £1). I guess it’s harder when you have no friends (in cheaper countries 😉 )

    Wonder if that Radeon RX 470 will end up in the Scorpio as some kind of bolted on APU

      • biffzinker

      Supposedly RX470 is in the Alienware VR backpack.

        But, but, it’s not having premium VR! Heh.

    • NoOne ButMe

    And because it is notebook 35W should be a very solid number correlate to real life power draw.

    • Chrispy_
    • 3 years ago

    Very quick maths says that the RX470 will be 71% quicker than a R9 270X

    (2.8/180)*110=1.71

      • chuckula
      • 3 years ago

      Given the number of compute units and purported clockspeed of the Rx 470 & 480 (about 1.266 GHz), you could come out with a theoretical boost of close to 2X over the 270X.

        • Chrispy_
        • 3 years ago

        No, that’s not how the math works. Clocks are utterly irrelevant, why would you even mention them?

        RX 470 performance = [i<]x[/i<] RX 470 Watts = 110 R9 270X performance = [i<]y[/i<] R2 270X Watts = 180 Translating the English "The RX 470 has 2.8X the performance per watt of an R9 270X" into math gives us: [i<]x[/i<]/110 = 2.8 * [i<]y[/i<]/180 Multiply both sides by 110 to give us [i<]x[/i<], the performance of the RX 470. [i<]x[/i<] = 2.8 * 110 * [i<]y[/i<]/180 [i<]x[/i<] = 308[i<]y[/i<]/180 [i<]x[/i<] = 1.71[i<]y[/i<] Subbing words back in: "RX 470 Performance equals 1.71 times R9 270 performance" That, however, is poor grammar, so I ran it though the [i<]GrammarNazi 9000[/i<] and it spat out this: "The RX 470 performs 71% faster than the R9 270X" You'll notice no use of clocks, architectural improvements, marketing futz or any other excuses.

          • NoOne ButMe
          • 3 years ago

          Except for AMD’s absured 270x power draw claims it is all good. 270x is not close to 180W… I think I saw tomshardware or techpowerup at 120-130W

          • anotherengineer
          • 3 years ago

          Where can I get GrammerNazi 9000 for my PC??

          • byaafacehead
          • 3 years ago

          Pshh both of you are over complicating things. Its this simple: 470 divided 270 equals 1.74. Therefore its will have 74% increase in power. Easy peasy

      • NoOne ButMe
      • 3 years ago

      I don’t know why techreport didn’t also report the 270x fps. Or note that AMD’s method was to use board power. Which is stupid as 270x is not close to it’s board power. For laptop parts as the power is meant for the manufacturers it is probably a real power draw.

        Is that a typo on the slide? AMD says ‘Polaris 10’ performance and then says ‘RX 470’, which is Polaris 11.

        It sounds like those numbers should really be for the RX 480?

          • Demetri
          • 3 years ago

          470 is a cut down 480. They’re both Polaris10.

            • 3 years ago

            I just hope they did have to or choose to cut it down as far as the 1070 is.

          Wondering if it will be called the GTX-1065 if it’s a harvested GP104 part, and then the GTX-1060 will be a GP106 that’s a fully-functional but much smaller die.

          We’ve heard that there will be 3 SKUs from the GP104, so it’ll either be 1060 and the GP106 will likely be called the 1050Ti or it’ll be 1065 and next die down will be the 1060.
