Along with this week’s teaser of the forthcoming Radeon RX 470 and RX 460 at E3, AMD also held a short press briefing about Polaris. The bulk of AMD’s presentation is going to be familiar to our readers who keep close tabs on AMD’s market strategy (in a word, VR), but this latest presentation also brought to light a few more details on the company’s two Polaris GPUs that I want to quickly touch upon.

First and foremost, AMD’s presentation included a slide with pictures of the two chips, and confirmation on their full configurations. The larger Polaris 10 is a 36 CU (2304 SP) chip, meaning that the forthcoming Radeon RX 480 video card is using a fully enabled chip. Meanwhile the smaller Polaris 11 (note that these pictures aren’t necessarily to scale) packs 16 CUs (1024 SPs). This puts it a bit below Pitcairn (20 CUs) before factoring in GCN 4’s higher efficiency. Meanwhile as is common for these lower-power GPUs, AMD’s slide also confirms that it features a 128-bit memory bus.

AMD is expecting Polaris 11 to offer over 2 TFLOPs of performance. Assuming a very liberal range of 2.0 to 2.5 TFLOPs for possible shipping products, this would put clockspeeds of a high-end Polaris 11 part at between 975MHz and 1220MHz, which is similar to our projections for RX 480/Polaris 10. Note that AMD has not yet announced any specific product using Polaris 11, however as we now know that RX 470 is a Polaris 10 based card, it’s safe to assume that RX 460 is Polaris 11, and the over-2 TFLOPs projection is for that card.

Second, briefly mentioned in AMD’s press release on Monday was the low z-height of at least Polaris 11, and it pops up in this slide deck again. There was some confusion whether z-height referred to the laptop or the chip, but the slide makes it clear that this is about the chip. So it will be interesting to see how thin Polaris 11 is, how that compares to other chips, and just what manufacturers can in turn do with it.

    Both rx460 and rx470 look promising to me. However, rx480 should have best theoetical value (tflops / $) Reply

    Going by their own benchmark of Steam VR, the 480 is about as fast as a 290. That's very underwhelming. I guess Hardocp was right. Reply

    390 not 290. And almost as good as a 980. For less than half the price.

    More importantly. Right smack bang in the mass market area where most people buy their GPUs.

    Also very interested in polaris 11 if the price is right and the tdp is low...

    Agreed. The RX 480's theoretical position on the price-performance curve will dominate NVidia in the market overall with current prices. NVidia won't let that happen of course. Rumors of 1060 specs are already making their rounds. Reply

    Steam VR is an unreliable benchmark. It's not even a benchmark really. It says cards like GTX 580 and GTX 560 Ti are VR ready (it is not) and other graphics cards score differently on each run - very differently. I've heard of a GTX 970 scoring between 6.1 to 7.9 (and everything in between) on the same machine. So don't put any stock in that. Reply

    I agree. My old i7 920 @ 4GHz and a overclocked 970 (about 1500MHz boost) gets me a solid 7.7 and nearly "very high" settings. No frame drops or frames under 90fps. It's a weak test. Reply

    Seems so weird to act as if you still don't know about P10/P11 when you've been to many AMD meetings in the last month and probably you have many RX 480/470 in the office under NDA. :) Reply

    I have followed Anandtech for many years, and have watched them slide into an Advanced Micro Devices basher, and very Intel/Nvidia pro website, not to mention, GAG, Apple. I no longer take anything this site offers in the way of reviews seriously. To even mention Hardocp is blasphemous, they've been trashing AMD for years, and wonder why they weren't invited to the AMD announcement..... If you want realistic reviews, go elsewhere, specifically where you aren't seeing a multitude of ads on the pages for Intel/Nvidia/Iphone, et al........... Reply

    AMD as a company is doing terribly. It is on the deathwatch over at Ars and on Forbes. It is hemorrhaging money, just sold off 11% of the company to the Chinese, and its R&D budget is down 30% in less than 3 years. it is hard to be excited for a company in such dire straits. Reply

    I remember when Apple was on the deathwatch, every week, every month, every year for almost a decade, people were creating clicks by writing negative articles about Apple. Major financial players were asking for liquidation of the company (hi Mike Dell!!) and pundits and internet "experts" alike were just counting down to the demise of Apple.

    Those who watched Apple closely at that time knew that things were turning around, because unlike a dying company, there was constant development going on, steady releases and interesting things happening.

    Dumb proclamations of "chinese owning 11%" of AMD mean nothing. Being on deathwatch means nothing. Budgets mean nothing. Capability, drive and product delivery does.

    AMD is still innovating, still making something new and interesting, still delivering those products. AMD is very much alive.
