AMD Radeon RX 480 Specs Detailed – 1.3GHz GPU Clock Speeds, 256GB/sec Bandwidth, 150W TDP
AMD has finally unleashed their Polaris based Radeon RX 480 graphics card, aimed at the wider mainstream market. Based on the company’s forth generation GCN architecture and the latest 14nm FinFET process node, RX 480 delivers a massive leap in transistor density and power efficiency at a mere $199, making it the most competitive Radeon graphics card in AMD’s history.
Much of the product’s specifications have been revealed by AMD. First off, the Radeon RX 480 includes 36 compute units (CUs), and assuming there are 64 stream processors per CU as per GCN standard, this brings us to a total of 2304 SPs on a clock speed that’s yet to be determined.
Also, AMD hasn’t named the specific Polaris chip that is powering the card, but taking into account the CU count, it would be reasonable to assume that it would be Polaris 10 SKU.
Further, the RX 480 would deliver over 5 TFLOPS of compute performance, and given we know the CU count as well, we can calculate the estimated GPU clock speed. This puts the GPU at 1.08GHz base clock and 1.3GHz boost clock speeds, which would be in the range of 10-30% higher than comparable Radeon 300 series cards. Which means the Radeon RX 480 could be a bit slower compared to the current R9 390.
However keep in mind that it doesn’t take into account Polaris’ enhanced features that are particularly designed to improve architectural efficiency. Which means RX 480 is likely to beat the R9 390 even at the lower bound of clock speed estimates. So we are actually looking at performance and architectural efficiency close to the R9 390X.
Speaking of the memory, AMD RX 480 is equipped with 8GB GDDR5, running across a 256-bit memory and expected to deliver a total of 256GB/sec of memory bandwidth. The card will be available in both 4GB and 8GB variants. Finally, the TDP is set at a sweet 150W which will be powered by a single 6-Pin connector that keeps the card running cool and quiet. Display connectors include three DP 1.4 and a single HDMI 2.0 port.
AMD will put the Radeon RX 480 on sale on June 29th at a price of $199 for the 4 GB and $229 for the 8 GB variants.
