PC Games Hardware had the chance to talk to Evan Groenke, Senior Product Manager for Polaris 10, about the configuration of the GPU used for the Radeon RX 480. Groenke made clear that Polaris 10 doesn't have 40 compute units - as some publication state - so that the Radeon RX 480 has the full configuration with 36 CUs (2.304 Shader).
Evan Groenke is Senior Product Manager for Polaris 10 and he was deeply involved in the development of Polaris. He should know if the full configuration of Polaris is 40 compute units (like some websites state) or 36. Groenke made absolutely clear that the latter is the case. Here is his full quote of the interview, you will find the whole audio interview at the end of the article.
PCGH: Is the P10 a 36-CU-part and no hidden additional CUs?
Evan Groenke: I can absolutely confirm with you right here, that Polaris 10 in its full configuration defined by the silicon is a 36 Compute Unit configuration there's nothing else hidden on that product that end users might be looking forward to unlocking. This is the pinnacle, the latest and greatest of the Polaris 10 product.
This also means that a possible Radeon RX 490 will not be based Polaris 10. It may be possible though that there is a new GPU revision coming up as RX 485. You may find our Radeon RX 480 review at PCGH.de and we have some more English articles on our dedicated landing page.
