AMD R9 Nano specs confirm 4096 cores

AMD’s upcoming tiny graphics card, the AMD Radeon R9 Nano, is set to feature the same number of cores as the flagship Fury X, according to a leaked specs list.

The news is particularly surprising as the new card, the release date of which is rumoured to be tomorrow, is smaller than the Fury X and has only a small air cooler rather than the large separate liquid cooler of the Fury X.

What’s more the card only has a specified TDP of 175W, which is 100W less than the Fury X.

To keep within that TDP those 4096 stream cores will run at a lower speed, with a maximum clock speed of 1000MHz.

This is only 50MHz slower than the maximum rated speed of the Fury X but it’s likely that the Nano will reach its top speed far less often as thermal limitations kick in.

Newly released slides from AMD also give an indication of the card’s likely performance, showing it will deliver around 70% the performance of the Fury X.

AMD Radeon R9 Nano Performance

The AMD Radeon R9 Nano is remarkable because the card is only six inches long. Although the Fury X is only 7.6inches, most other cards of similar performance levels are around 10inches long.

It also only requires one 8-pin PCIe power connector so it is potentially the ideal card for really compact PCs.

AMD Radeon R9 Fury X and Nano HBM

The reason it is able to be so small is its use of High Bandwidth Memory (HBM), which has memory chips stacked on top of each other rather than arrayed around the GPU. The result is that the GPU+memory footprint is around a third of non-HBM graphics cards.

Despite its diminutive size, expect the R9 Nano to still demand a fairly high price. We suspect it’ll come in around the same price as the GTX 980 at around £300-£400.
