finally we receive the specifications for the first Polaris GPU to hit the markets but the big question is in light of both the 1070 and 1080 releases how much traction will this mid to your graphics card have let's find out let's run through the specifications of the card and we'll assess performance as we go along perhaps the most noteworthy improvement of the 480 is in its architecture we are so excited at the 40 nanometer of graphene for transition right because it brings much higher performance at much lower power which is always really really sweet thing for for gamers for workstation for VR and all these incredible use cases we're talking 40 nanometer FinFET transistor design a substantial jump from the 28 nanometer architecture of AMD's GC and 1.2 technology both the r9 380 and 390 utilize this process we'll be using both of these cards to compare with the RX 480 the 480 will most certainly feature 2300 for stream processors roughly equivalent to CUDA cores on a video side placing it directly between the r9 380 and 390 totals this number is calculated by multiplying the number of compute units by the number of stream processors per compute unit which has been 64 throughout the existence of GCN while this number for the 480 might seem a bit underwhelming it's important to take into consideration the affirm engine architectures involved with these chips as having smaller transistors allows for a much larger amount of them to be packed into a similarly sized die the standard we can use to estimate graphics card performance without using in-game benchmarks is floating-point performance calculated in teraflops this is essentially the IPC of a GPU in the case of the RX for 80 AMD's chosen to keep this number basically a secret so what's inside on our X 480 we have over 500 flops of computing in this beautiful card however what we can do is produce a very close estimate to the actual number that we'll see later this month by using the r9 390 and 380 as references taking into account the 50% reduction in transistor size a TDP of 150 watts half the TDP of the r9 390 and teraflop values of 5.1 and 3.5 respectively we can safely assume that the arcs for will likely fall above the 5.1 teraflop performance of the 390 and what do you know this falls in line with AMD's claim and beyond the specification it is also our most power efficient GPU ever it's up to 2.8 x performance for what improvement or art regeneration it's enabled by both the FinFET technology that we work with and also architectural improvements amazing amazing performance improvement in fact in my personal opinion based on the efficiency factor in stream processor count of the card the RX 480 will likely meet or exceed the rating of the r9 390x at 5.9 teraflops in terms of memory we're looking at eight gigabit per second gddr5 which is actually quite high for g5 memory and a 256-bit memory bus memory size will likely vary some cards will offer four gigabytes of vram and others eight gigabytes it's highly probable that the base reference card will only offer four gigabytes and you'll have to pay a premium of sorts for the eight gigabyte version we are slowly becoming mainstream and AMD is not backing down so we wanted to deliver a high-performance low-cost low-power solution to democratize vr which can make we are possible for anyone who wants it it can drive VR into detail it can hit system price points PC price points that can be everywhere in retail and it can grow the market to over 100 million consumers and also drive VR application development content development in a large-scale fashion they're claiming $500 VR performance from the RX 480 which is a bold claim and it would actually put it in the same category as an R 9 nano I remain skeptical of this claim just as I did for invidious claim of the 10 70s VR performance and just performance in general I don't really take what companies say about their own cards at face value and I honestly don't believe that you should either I invite you to check out our reviews of these cards once they're released before formulating adamant opinions on any of these cards pre-debut finally price how much will this budget powerhouse cost well according to AMD only 199 bucks so about the same price as current r9 380 for you go by graphics card however it does appear that the rx for you will perform about 50 percent better than its 380 counterpart making it quite the bargain for the red team so that brings the conclusion my Polaris unreal today and latest architecture is a giant giant step forward for PC gaming and VR and what we have revealed to you today is its capability in in VR and it's and its price points you will see a lot more information about the entire Polaris GPU stack coming out in the neck over the next few weeks ladies and gentlemen thank you and also I want to thank all of the engineers who worked on Polaris tirelessly over the last two years to get us to this day thank you expect to hear more from Andy in the coming weeks and stay tuned for the release of the RX 480 June 29 if you like the content of this video be sure to give it a thumbs up give it a thumbs down while you're not feel the complete opposite be sure to click the subscribe button if you haven't already and stay tuned for a future PC build here on the channel I believe this will be our 13th we're on a roll folks this is science studio thanks for learning with us you
