MD says the majority of its buyers prefer GPUs in the 100 to 300 dollar range pretty fair bet I think they were saying about eighty four percent of their buyers are in that range and so with Polaris their focus shifted away from halo products like the high-end stuff down to more mainstream focused segments and that makes sense for a company trying to fight where they can make the most money so that's what Andy's looking at for the RX 470 and 460 which as of today we have a little bit more news for you but it's not that much more over the review of the RX 480 which had a table for specs of the 417 460 in it if you did not see that the 480 is being left to focus on 1440p gaming and the 470 is looking at the 1080p segment first the RX for 70 is the polaris 10 GPU and has the same architecture as the RX 480 including compute preemption and asynchronous shaders but it is a cut-down version in terms of stream processor count and the clock rate the RX 470 will host 32 is see used as opposed to the 36 use of the RX 480 and that puts us at 2048 stream processors knowing that each see you has 64 stream processors this isn't actually new information so they didn't officially say this thing has 2048 stream processors previously but it was pretty obvious because they did tell somebody to use a head so that was calculable pretty easily the new stuff though is the clock rate so the RX 470 will operate at 1206 megahertz boosted and 926 base and that's what the 2048 processors it's got 128 TM user texture map units on the 470 and for perspective the 480 had 144 of those TM use its operating with 32 ROPS and memory operates on a 256-bit interface with a 6.6 gigabit per second affective memory speed it's hosting 4 gigabytes of gddr5 and that's with a 211 gigabyte per second memory bandwidth display interfaces include the hdmi 2.0 spec and DisplayPort support for HDR and HB r 3 up to 1.4 DisplayPort and TDP is listed as 121 wats just as a reminder don't fall for the trap that a lot of people fall for you cannot compare TDP cross architecture or across brand so when we talk about a 120 watt TDP for the RX 470 you can't turn around and say that's equal to whatever nvidia cards may have a 120 watt TDP of 1060 what have you or 150 watt as the case may be this is more of a measurement of the cooling potential required to keep that or the cooling power required to keep the chip at a manageable temperature it's not just plug it into a no scope and the output is 120 watts it's not how it works so you will need to look for our power testing with the 474 a look at its actual power draw just as you'd have to look at it for the 1060 or what have you but TDP is 120 watts the only thing you can compare that against is internal brand internal architecture tdps that would be against the 480 or something like that in terms of the memory subsystem the RX 470 has the same memory subsystem as our X 480 so that means it's got the same Delta color compression it has other similar optimizations in the memory pipeline that reduce the power consumption of memory and a non trivial way is forty percent lower power or so versus previous generations and that helps with the overall reduction of power and that lower TDP we're talking about Delta color compression is the same the way the memory works is the same as the 480 so only thing that's really changed here is the capacity the bit width and things like that for the interface and in terms of the release date the RX 470 will be available effective on August fourth and the price is undetermined ahem the decided to do another news announcement of these cards because they missed their mid-july and end of July release dates pretty standard in some regard for these these types of products but they missed those release dates they put out into the other news announcement today with the TMU account things like that but the price is not yet known in terms of performance AMD is saying that the 470 should be about 1.5 x faster than the 270 which is two generations old now one to depend on how you count the architectures so 1.5 x over that we have the card yet but hopefully we'll get one for review the RX 460 will be on Polaris 11 it's got 14 C use with 896 stream processors and it's clocked at twelve hundred megahertz of boost and 1090 base the RX 460 will have 50 60 M use and 16 rob's so it's about half of what we're seeing for the most part of the 470 and performance is up to 2.2 teraflops again Polaris 11 kind of indicates that memory runs at an effective seven gigabits per second on two gigabytes or four gigabytes of gddr5 with the interface 128 bits wide that puts memory bandwidth by the way at 112 gigabytes per second we've seen some confusion lately as well as to how memory bandwidth is calculated to just as a reminder it's pretty simple but you have to do it right order first divide the bus width and bits by eight that converts bits two bytes eight bits in a byte and then multiply the actual memory speed not the same as the effect of speed we see here which is seven gigabits per second multiplied the actual memory speed by the quotients of whatever the interface / 8 equals you multiply those numbers then you multiply again by 24 DDR and then again by 24 gddr5 which gives us 112 gigabytes per second TDP for the RX 460 is it less than 75 watts so it can function entirely off of PCIe and price for this card is also unknown it will be releasing on august eighth we should have the price for you hopefully a day or two before then but if it's not something we can publish yet then I guess you'll know about it on launch day so August eighth for the 460 that's the low end card and August fourth for the 470 which is sorta low end but in that mid-range market I would assume closer to one hundred fifty dollars for the 470 which would put it in competition with Nvidia's at 950 at least as of today and the 460 is probably going to be closer to competition was something like the 750 Ti in terms of just a brand versus brand stack up notebooks are also important though so with the 980 and video was able to move that chip to notebooks in its entirety there was not a cut-down version of 980 and Andy is doing the same thing now this is because the TDP of these chips these days is lowering enough that can be put into a laptop without making an M version ie9 ATM or for ATM or what what have you so that's been kind of moved away from Andy is going to be bringing its full Polaris chips the 417 460 certainly into laptops and they're not cut down models the notebooks will have a lower TDP on the chip versus the desktop counterparts just nature of thermal throttling and concerns with laptops pretty normal stuff so it's it is on the manufacturers to make sure these laptops are cooled of course as always but the TDP is low enough that they're ditching the M suffix for this at least immediate stack up of GPUs coming out so they'll be leveraging the 417 462 hopefully regains on that notebook arena that's been basically all intel and nvidia the last few years in BO smarter than a couple of APU products as far as testing I'm hoping to look at both 4 & 2 gigabyte versions of the 460 so that we can see what that difference actually looks like in the real world kind of like we did with the 484 and 8 gigabyte versions I'm thinking it'll probably ROPS limited and that 2 gigabytes is about where we'll see peak performance though there may be some titles where 4 gigabytes makes sense for one percent loads and things like that so you can see our RX 488 vs. 4 gigabytes benchmark for a look at that in terms of the rest of this stuff that's that's really where we're at with this so its fourth and eighth is what you need to look out for waiting on
