AMD Reveals More RX 470 and 460 Specs
Samuel Wan / 4 years ago
Yesterday, AMD surprised everyone with their reveal of the RX 470 and RX 460 graphics cards. Set to arrive below the $200 price point of the RX 480, the new Polaris GPUs are meant to address the 1080p gaming and MOBA markets respectively. Today, we’re getting some more detailed specifications for the respective Polaris 10 and Polaris 11 GPUs.
Polaris 11 is the big highlight as we haven’t received any information for that GPU yet. The chip features the new GCN 4.0 architecture with 16 CUs. This gives us 1024 SPs, the same amount as the R7 370. Performance comes in at over 2 TFLOPS which means clocks over 1Ghz and likely similar to Polaris 10. If we extrapolate the same IPC gains as we are expecting from the RX 480, we should see Polaris 11 GPUs peaking around the R9 270/270X. In 3DMark Fire Strike, the RX 480M scored 4070 which is a tad low but expected of a lower clocked mobile version of Polaris 11.
For Polaris 10, we can now confirm that this is the GPU powering the RX 470. The card will likely be cut down from the 36CU RX 480 to likely 28-32CU, offering about R9 380X to R9 290 performance. According to AMD’s own internal benchmarks, the card scores 9090 in regular Fire Strike, placing it near the R9 290. For a card under $200, and likely around $150, this will be the go-to card for 1080p gamers.
With these 3 cards, AMD has largely locked up the mainstream market until Nvidia responds with their own mainstream Pascal cards. Offering superb price to performance with a highly efficient lineup, it will be interesting to see how the rest of the year will play out.
