Intel Gen12 Xe iGPU Could Match AMD's Vega-based iGPUs
Intel's first integrated graphics solution based on its ambitious new Xe graphics architecture, could match AMD's "Vega" architecture based iGPU solutions, such as the one found in its latest Ryzen 4000 series "Renoir" iGPUs, according to leaked 3DMark FireStrike numbers put out by @_rogame. Benchmark results of a prototype laptop based on Intel's "Tiger Lake-U" processor surfaced on the 3DMark database. This processor embeds Intel's Gen12 Xe iGPU solution, which is purported to offer significant performance gains over current Gen11 and Gen9.5 based iGPUs.
The prototype 2-core/4-thread "Tiger Lake-U" processor with Gen12 graphics yields a 3DMark FireStrike score of 2,196 points, with a graphics score of 2,467, and 6,488 points physics score. These scores are comparable to 8 CU Radeon Vega iGPU solutions. "Renoir" tops out at 8 CUs, but shores up performance to the 11 CU "Picasso" levels by other means. Besides tapping into the 7 nm process to increase engine clocks, improve the boosting algorithm, and modernizing the display- and multimedia engines; AMD's iGPU is largely based on the same 3-year old "Vega" architecture. Intel Gen12 Xe makes its debut with the "Tiger Lake" microarchitecture slated for 2021.

Only thing Intel can do is bribe game developers (like NV has done before - TWIMTBP) to "optimize" their games to run faster on Intel GPU arch (or artifically slow down on non-Intel GPU). They have done that in the past with CPU so why not.
Fanboy stuff aside, more players means more options so I'm happy. This gen I bought an AMD CPU + NVidia GPU, maybe next will be Intel (probably my next laptop), so I'm cheering for them - I rarely game on my laptop, but a nice iGPU is always welcome for some casual gaming outside my home.
I'm not saying it will be. After seeing the new AMD APUs, and having tesed the Ryzen 2200G vs i5-4690K iGPU myself, I decided my next laptop would be AMD based. Now I just saw that I don't need to narrow down my choice because Intel might be back in the iGPU game.
As someone above mentioned, AMD are not even focusing on the iGPU uarch in mobile Ryzen 4000 series. They just significantly bumped the clocks, and together with the new high-speed DDR4 support in Ryzen 4000, these little chips will still pack a punch.
Also, last time I checked intel's GPU drivers were even worse than AMD's. This can change any time now but I wouldn't bet too much on it.
My bet is mobile Ryzen 4000 will hold up against anything intel has to release this year, or even the next. If the friggin virus don't screw fabs' latest 5nm process I expect intel to lose even the next year due to the process inferiority itself.
Heck, even 2700U could decode and output 4K@60fps 10-bit color in hardware. What was the cheapest intel iGPU that can do this?
The implementation of Vega is likely their best effort within the constraints of a mass-market mobile chip at the time of its design- one where die area needs to stay reasonable (without sacrificing cores or maximum CPU performance, which would necessitate an expensive second H-series die) and development schedules for GPU architectures don't align well with APU development schedules (RDNA likely wasn't ready when Renoir was designed). Still, there are obvious roads towards better iGPU performance now and in the future, mainly in implementing RDNA with its near 50% perf/CU increase (when comparing the 5700 XT vs. Radeon Vii which are on the same node) - which was obviously ready when design work on next-gen APUs started even if it wasn't for the 4000-series. If they get LPDDR5 into the next gen chips (which is unlikely given that it just arrived in mobile, LPDDR4X just hit PCs, and LPDDR4X hit mobile several years ago) that's another 25+% bandwidth increase.
My entire post was about mobile processors. IDK how you got the idea of 35W "mobile" CPU, although back then this was pretty low number. We really don't know if RDNA was made with mobile in mind, or at least I don't. Porting RDNA to mobile may not bring much benefits if it was not tailored for mobile platforms in a first place.
Yep thats right once RDNA is implemented into these APU's there iGPU is once again way behind.
Meanwhile the momentum of Xe discrete seems to have died down right around the time Navi released and actually brought a perf/watt jump. I think Intel is slowly but surely seeing this is yet another area where they lack the node and are just behind the curve... even the curve of the GPU underdog, go figure.
But as this news post says, it's possible that Tiger Lake Xe iGPUs can match it - though frankly I doubt that given Intel's driver track record. They have often managed to get close to AMD iGPUs with Iris Plus SKUs in synthetics like 3DMark, yet have consistently lagged far, far behind in real-world gaming. I expect a push for better and more frequently updated drivers with Xe, but it'll take time to get them out of the gutter. And by then, RDNA APUs will be here.
