For those unfamiliar with that name, Crystal Well is what we know now as Intel’s Haswell CPU lineup; back then, the lineup’s integrated graphics was known as the Iris Pro 5200, which in turn was a part of the top-of-the-line CPU at the time, the Core i7-4770K.
While it may seem like Koduri is merely making a passing remark about Xe-HPG, there is actually some truth behind it. Thanks to PC World, we know that the Iris Pro 5200 had a UL Fire Strike’s graphics score of 1450 points. Multiply that by 20, and the number you’re looking at is 29000 points; that’s more or less on the level of the aforementioned RTX 3070.
That said, Koduri’s tweet is still, nevertheless, cryptic, and much of what we’ve talked about is still unconfirmed and mere speculation of what we can expect from Intel’s Xe HPG. So, until an official announcement by Intel, take this news with a large grain of salt.
