AMD's Polaris 10 to deliverR9 390X/390 horsepower at half the wattage for less than $299. Polaris 11 to be AMD's console killer GPU, deliveringGeForce GTX 950 performance at only 50W. This is only the tip of the icebergaccording to the latest leaks that have hit the web from multiple sources, so buckle up as we break AMD's Radeon 400 series down for you.
Let's start off with the leaked specifications whichhave been reported by VCZ & TPU.Both of which claim to have corroboratedthe informationindependentlythroughtheir own industry sources. So it's very likely we're looking at the real deal here. Still,please remember to take this with agrain of salt.
AMD Polaris 10 Features 32 CUs & 5.5 TFLOPS
To Deliver R9 390X/390 Performance At Half The Wattage & Less Than $299
AMD's Polaris 10 GPU reportedly features a 256bit GDDR5/X memory interface & cards based on the chip will feature 8GB of memory. The GPU packs 32 GCN 4.0 compute units for a total of 2048 stream processors, the same number found in AMD's current R9 380X. However,Polaris 10cards arereportedlysignificantly faster and will deliverR9 390X/390 class performance. Leaks also pit the MSRP at lessthan$299at launch.
According to today's leak the GPU is rated at 5.5 TFLOPS, which is 0.1 TFLOPS shy of the 2816 SPR9 290X. An impressive feat considering the 290X is a ~290Wcard with 37.5% more GCN stream processors and a memory interface that's twice as wide. The card is also reportedly rated at less than 150W. According to a previous leak from Benchlife Polaris 10 graphics cards will be rated at around110W-135W depending on the GPU configuration and clock speeds. Interestingly, according to VCZ this 5.5 TFLOP GPU is not even a desktop class chip but amobility variant. This would bring R9 390X/390 class performance to notebooks.

We received the exact same specifications just few days ago. Although it was noted that those are specifications for mobile GPUs, so you may want to takethis into consideration.
A 5.5 TFLOPS rating would put Polaris 10's GPU clock speed at around 1350Mhz, a whopping 39% increase over its predecessor the R9 380X. This is unsurprisingly thanks largely to the brand new FinFET manufacturing process which is capableof significantly higher clock speeds without sacrificing leakage. This as we've seen has alsoallowed Nvidia to boost clock speeds on its Pascal GPUs by a similar margin.

AMD Polaris 11 Features 14 CUs & 2.5 TFLOPS
To Deliver R9 270X Performance At Less ThanA Third Of The Wattage
Polaris 11 on the other hand will feature 14 GCN 4.0 compute units for a total of 896 stream processors. The GPU features a 128bit GDDR5/X memory interface and Polaris 11 cards will feature 4GB of memory. The GPU is rated at 2.5 TFLOPS and a TDP that's less than 50 watts.
That's0.5 TFLOPS north of the 110W R7 370 at less than half the wattage & exactly the sameperformance ofthe 180WR9 270X. According to the latest leak Polaris 11 will replace the Bonaire GPUs powering the R7 360 and 260 series cards but will outperform the larger Pitcairn powered 370 and 270 series cards. Again, according to VCZ this is also a mobility variant of Polaris 11 that will power thin gaming notebooks.
