The official specifications for AMD’s upcoming mainstream Radeon RX 470 and Radeon RX 460 have been leaked to the web as slides from AMD’s official press presentation ahead of their early-August product launches.
Let’s start with the Radeon RX 470. This card is based off the same “Ellesmere” Polaris 10 silicon as AMD’s Radeon RX 480. It features 2048 stream processors across 32 GCN compute units, 128 TMUs, 32 ROPs, and 4 GB of memory acorss a 256-bit wide GDDR5 memory interface.
The card has a GPU clock speed of 926 MHz and boosts all the way up to 1206 MHz. This gives us a maximum compute performance of 4.9 TFLOPS. The RX 470 will be available with 4 GB of GDDR5 memory, but AIB’s could offer 8 GB versions. The memory is clocked at 1650 MHz, which would give us a bandwidth of 211 GB/s. The card has a typical board power of 120W, so it will use a 6-pin PCIe power connection.
Looking at the performance graph above from AMD, which says “brilliant HD Gaming” (1080p), the card should be 1.5 – 2.4 times faster than AMD’s R7 270 in games.
The Radeon RX 460 will be based on the “Baffin” Polaris 11 silicon, which features 896 stream processors, 48 TMUs, 16 ROPs, and 4GB of memory across a 128-bit wide GDDR5 memory interface.
It will have a core clock of 1090 MHz, with a boost up to 1200 MHz. The memory is clocked at 7 Gbps (GDDR5-effective) which works out to 112 GB/s of memory bandwidth. The TDP of this card is rated at <75W and will completely rely on the PCIe slot for power.
This card is designed for e-sports gaming and should be 1.2 to 1.3 times faster than the Radeon R7 260X in titles like DOTA 2, Counter-Strike GO, Overwatch, Rocket League, and even GTA 5.
The RX 470 will be available August 4th and the RX 460 will follow shortly after on August 8th.
