If anyone needs a reminder on the depth of commitment Intel has in the dGPU space, this should serve well.
IMHO all of Intels dGPU activities are nothing but crude attempts at shareholder appeasement, nothing to do with actual users or clients of Intel tech.
Looking at the product range and how it's evolving they clearly aren't interested in acutally capturing market share, as they seem to loose money (or fall way below prescribed margins) on every GPU sold. It's all show and the only reasonable audience for that show must be actual or potential shareholders/investors.
Intel currently needs to put in quite a few more transistors, bandwidth or just hardware resources to draw close to Nvidia or AMD offerings and that isn't sustainable. So expanding the product range to professional variants of the B580 or going for a B7x0 can only mean enlarging the financial wounds for every unit sold. Small wonder they all seem paper launches, because Intel does understand the bottom line, even if they don't know how to meet it any more.
Please try to believe me that I want to be wrong in the interest of more competition and better customer value. I just don't see the data points to sustain that dream.
