Kicking off at this moment is AMD’s Computex 2016 keynote. The company has multiple announcements scheduled this evening, but we’re going to jump right into an area that has been of extreme interest for many of our readers: GPUs.

Ahead of this evening’s event, AMD sent out an email to the press teasing the first of their discrete Polaris architecture based cards. Called the Radeon RX 480, AMD has unveiled much of the product’s specifications, but also its price and availability. When the card hits the streets on June 29th, it will be starting at the crucial mainstream battleground price point of $199.

First off, the RX 480 will include 36 CUs. If we assume 64 stream processors to a CU – the GCN standard – then this brings us to 2304 SPs. AMD has not named the specific Polaris GPU being used here, but given the CU count I believe it’s reasonable to assume that this is a Polaris 10 SKU, as I’ve already seen Polaris 11 and it’s a very small chip better suited for notebooks.

AMD also revealed that the card would offer over 5 TFLOPs of compute performance. Given what we know about the CU count, this allows us to estimate the GPU clockspeed. This puts the lower bound of the GPU clockspeed at 1.08GHz and an upper bound (6 TFLOPs) at 1.3GHz, which would be in the range of 10-30% higher clocked than comparable Radeon 300 series cards.

In terms of raw numbers this puts the RX 480 just shy of the current Radeon R9 390. However it also doesn’t take into account the fact that one of the major focuses for Polaris will be in improving architectural efficiency. I would certainly expect that even at the lower end of clockspeed estimates, RX 480 could pull ahead of the R9 390, in which case we’re looking at a part that would deliver performance between the R9 390 and R9 390X, with final clockspeeds and architectural efficiency settling just how close to R9 390X the new card gets.

On the memory front the card is equipped with 8Gbps GDDR5, running along a 256-bit memory bus. This is the typical bus width for AMD x80-series cards, and the high clocked 8Gbps GDDR5 means that we’re looking at a total of 256GB/sec of memory bandwidth to feed the RX 480’s GPU. AMD’s partners will be offering both 4GB and 8GB cards, and for the purposes of this teaser I assume that pricing information will be for the 4GB card, with 8GB serving as a premium option.

Finally, AMD has also revealed the TDP for the RX 480, stating that it will be a 150W card. As Polaris is built on 14nm FinFET, we’re seeing first-hand the benefits of finally making the long-awaited jump off of 28nm, as this means we’re looking at Radeon R9 390 series performance in a card that, on paper, consumes only a bit more than half the power. This also puts the RX 480 right in the sweet spot for mainstream cards, as 150W has traditionally struck a good balance between performance and power consumption that allows for a fast card that doesn’t require aggressive cooling, and is more compatible with OEM computer vendor case & cooling designs.

Cementing its place as a mainstream card, the RX 480 pricing will start at $199. This is an aggressive and heavily fought over price point that has traditionally defined the mainstream segment, attracting buyers who want great 1080p gaming performance that sub-$150 value cards can’t offer, without moving up to more expensive (and power hungry) $300+ cards. In this sense the RX 480 is a direct replacement for the R9 380, AMD’s Tonga-based card that hit the market roughly a year ago at the same price. Going by the raw numbers alone, RX 480 would be 40% (or more) faster than the R9 380.

Meanwhile I won’t speculate too much on the competitive market from a teaser, but it’s worth noting that this is nearly half the price of NVIDIA’s currently cheapest Pascal card, the GeForce GTX 1070. Interestingly both cards have the same 150W TDP, but looking at the throughput figures it does not look like RX 480 is meant to offer quite as high performance as NVIDIA’s card.

Moving on, along with teasing the RX 480’s specifications, AMD’s teaser also laid out their marketing plans for the card. We’re previously talked about how both Oculus and Valve/HTC were encouraging developers to treat VR like a fixed platform, and setting minimum hardware specifications to go along with that. On the AMD side those specifications called for a Radeon R9 290, which the RX 480 should be able to beat.

As a result AMD is planning on heavily promoting the VR aspects of the RX 480, as it brings the necessary performance down from a 250W, $300+ card to a 150W, $200 card. In fact AMD is claiming that VR performance will be closer to $500 video cards, in which case we’d be looking at performance closer to the Radeon R9 Nano, a Fiji based card.

With all of that said, the video card is just one component in the total price of a VR system – you still need the headset – but on the PC side it has also been the most expensive component. Consequently, AMD sees cheaper video cards that offer good VR performance as being important to bringing down the total price of a VR-ready system, and will be promoting the RX 480 as the prescription for entry-level VR needs. From a business perspective, AMD is ultimately expecting VR to be a fast-growing market, so the company wants to make sure they don’t miss out and have more VR-capable cards on the market as quickly as they can.

Along those lines, AMD’s release also makes note that at least one model will be “both HTC Vive Ready and Oculus Rift certified,” though no further details are being offered at this time. Whether this is just a certification matter or if there’s going to be something special about this model (e.g. connectors) is open to speculation.

Finally, now that they’ve revealed the price and much of the specifications of their first Polaris card, AMD is also releasing more details on their overall development and market positioning strategy with Polaris. As AMD has hinted at in the past, Polaris is being specifically developed for and aimed at the mainstream market. AMD wants to recapture lost market share – especially in laptops – and the large mainstream market is seen as the best way to do that. AMD is calling this their “water drop” strategy, and I expect we’ll hear a bit more about it tonight, including the meaning behind the name.

And with all of that said, it looks like we’re going to have a lot of AMD to talk about on June 29th. So until they, stay tuned.

    You do realise that TDP is not Power consumption right?
    1070 is going to use an 8pin power connector which should give it room to use up to 225w so it deffinitley uses more than 150w, the rx480 has a 6pin connector so max power is 150w which means it'll use less than 150w... just guestimating but i'd expect actual power usage under load of the 1070 to be between 150w & 180w while the rx480 will probably sit between 120w and 140w... anyway we will hav to wait till actual hands on reviews come out to get more exact figures but dont look at tdp as anything more than a rough guide when it comes to power use.
  • HollyDOL - Wednesday, June 1, 2016 - link

    Well, at least EVGA on their site claims "Max Power Draw: 150W" ... http://www.evga.com/Products/Product.aspx?pn=08G-P...
  • bucketface - Wednesday, June 1, 2016 - link

    Ok, having looked more closely at gtx1080 power draws, they do seem to average at about 180w, peaks are still over 200w (as an aside EVGA look to be offering an OC'd one with what they claim as max power of 215w, so looks like thay will be trying to push the limits)
    so maybe the 1070 does average around the 150w mark and just needs the extra room of the 8pin for peaks.
    That said the rx480 should be averaging somewhat less than 150w due to the limitations of the 6pin connector.

    TDP is average maximum draw. There's no place the energy goes other than heat.
  • extide - Tuesday, June 7, 2016 - link

    Yep, all of the energy used by the GPU turns to heat. It doesnt turn into motion, or light, etc, so it MUST turn to heat. Some of the power is used by the fans, of course, but other than that, its heat!

    ~15% less performance than a 1070 @ ~48% less price.

    it's a no brainer for those who are balancing all available factors
  • lakedude - Wednesday, June 1, 2016 - link

    Exactly, nVidia is likely better but not worth the extra cost if those numbers hold up. Were I still single with disposable income I'd be buying nVidia because better. Now that I'm Al Bundy the RX480 is much more tempting because value.
  • Valantar - Wednesday, June 1, 2016 - link

    Where on earth are you getting 15% less performance than the 1070 from? To quote PCPer's review of the GTX 1070: "The GTX 1070 based on Pascal is never less than 53% faster than the GTX 970 when running at 2560x1440 and is nearly twice the performance in Rise of the Tomb Raider!" They also show it performing around 50% above the 390X. The R9 390 performs roughly on par with the 970, but beats it in a few situations. This seems to be expected to slightly outperform the 390. In other words, I'd expect this to perform at 60-70% of the GTX 1070, not 85%. Even with that considered, it's good value, but nowhere near what you're saying.

    And no, I'm not an Nvidia fanboy. I've never owned an Nvidia card, and my current PC has a Fury X in it. I'm simply opposed to making bogus claims, especially ones that build up unrealistic expectations of underdogs you really want to succeed.
  • Tewt - Wednesday, June 1, 2016 - link

    I'm not sure how Anandtech measures but based on the info so far, just looking at teraflops, about 6.4 for the 1070 and over 5 for the RX480, can net you anywhere from 20% to 15% less performance. I used 5.2 teraflops(we don't know exact values yet) for AMD so a simple calculation of 5.2/6.4 gets you 81%.
  • Tewt - Wednesday, June 1, 2016 - link

    and yes, that is an oversimplification so I will still wait for actual benchmarks of retail units but just at a quick glance of the info available, I agree with at80eighty.
