Intel's Raja Koduri Teases Xe-HPG (DG2) GPU with 512 Execution Units
Today, Mr. Raja Koduri, senior vice president, chief architect, and general manager of Architecture, Graphics, and Software at Intel, has teased Intel's upcoming Xe-HPG (DG2) gaming GPU on Twitter. Sharing a die shot of Intel's Xe-HPG design with 512 Execution Units (EUs), Mr. Koduri has highlighted the progress that the company is currently going through. The Xe-HPG will represent the company's efforts of going into a very competitive discrete GPU market, dominated by a duopoly of AMD and NVIDIA. The Xe-HPG design pictured below is representative of a maxed-out SKU with 512 EUs, translating into 4096 shading units. This model is expected to be paired with 16 GB of GDDR6 memory.
"From jittery journeys to buttery smooth" - it is quoted in a Tweet of Mr. Koduri. This doubles down on the efforts Intel is putting into creating a GPU and the difficulties that the company is facing. It is also noted that there remains a lot of work in form of driver coding and a lot of game optimizations, which are very important for the new GPU. You can check out the complete Tweet below.
Update 07:55 UTC: According to @_rogame, who has performed calculations of die size by placing the image in the leaked PCB scheme of the DG2 designs, we have information about rough die size. The estimations are currently that the die is measured at 22.3 mm lenght and 8.5 mm width, resulting in 190 mm² area.

Raja KoduriXe-HPG (DG2) real candy - very productive time at the Folsom lab couple of weeks ago. "From jittery journeys to buttery smooth" said @rogerdchandler - lots of game and driver optimization work ahead for @gfxlisa's software team. They are all very excited..and a little scared:)

"And Vega is doing great in all Zen based APU's"
The newer Vega based APUs aren't the same ones designed by Raja. AMD made revisions to massively increase performance per watt since Raja left. Talking a 70% increase in performance per watt that Raja had no hand in. The original Vega based APUs were pretty meh.
When you compare what Raja did to what the other team at AMD did (Polaris, RDNA) you can pretty easily see why Raja is no longer at AMD.
So for work Intel might be an excellent GPU, i will buy this in an instant even if it's average in games.
Progress is good but they're not quite there for serious gamers yet with plenty of issues still to be ironed out with Xe80 and Xe96 graphics in the i5 and i7 respectively.
I truly wonder what Raja is really doing different right now other than some improvements in power delivery to suit the node it gets baked on, and a major expansion of the good old Intel Iris-budget version that could be so much more. The reason... cost effectiveness. In hindsight you could wonder if that was a good move and if the idea should not have been expanded upon...

I mean... what IF... they had expanded this technology to a chiplet design to reach higher core counts instead of chasing 5Ghz for sales charts.
