Intel Says Its Upcoming Gen12 GPUs Will Feature Biggest Architecture Change In A Decade
Intel is slowly realizing plans to "one up" its GPU game starting from first 10 nm Ice Lake CPUs that feature Gen11 graphics, equipping users of integrated GPUs with much more performance than they previously got. Fortunately, Intel doesn't plan to stop there. Thanks to the recent pull request found on GitLab Mesa repository, we can now expect to receive biggest GPU performance bump in over a decade with the arrival of Gen12 based GPUs, found on next generation Tiger Lake processors.
In this merge request, Francisco Jerez, member of Intel's open source Linux graphics team, stated the following: "Gen12 is planned to include one of the most in-depth reworks of the Intel EU ISA since the original i965. The encoding of almost every instruction field, hardware opcode and register type needs to be updated in this merge request. But probably the most invasive change is the removal of the register scoreboard logic from the hardware, which means that the EU will no longer guarantee data coherency between register reads and writes, and will require the compiler to synchronize dependent instructions anytime there is a potential data hazard..."
Planned for release sometime around 2020/2021 (with Tiger Lake), Gen12 graphics features a complete overhaul of Execution Unit in a way we haven't seen since i965 debut. There will be less hardware logic that checks data for coherency, possibly resulting in lower latency and higher performance. That workload will shift from logic built into hardware, to compilers for them to figure out if data is correct or not, resulting in less wasted GPU clock cycles dedicated to that function.

Clearly the next step is throwing an HBM on the die as well. AMD could do that quite easily with their multi-chip processors. Intel is doing work on 3D chip integration, maybe that technology will come to bear on a "new" Iris Pro.
I have to laugh that we're just now seeing Intel put out something that can beat my i7-5775c at graphics performance. About time!
hiringpoaching so many former AMD engineers...news.bbc.co.uk/2/hi/technology/7902989.stm
So 50/64 = 78% of performance.... 22% less...
Math is hard, I get it.
And you compare it to 15-25w intel cpus ment for mobile on a game notoriously bottlenecked by cpu performance.
Pretty sure people call that intellectual bankruptcy
Granted that's intel 11 gen graphics is only in their icelake platform but amd has mobile platforms as well.
If you want to be a little more honest
try a I7-1065G7 vs Ryzen 7 3700U both are part of the upper end of their mobile segments and have tdp of 15-25w
And Intel's support is shit. No WDDM 2.6 or even 2.4/2.5 for Haswell IGPU. Didn't receive any update for IGPU through out either 2017/2018, then only recieved 1 update in 2019 with driver date of 2018.
I found it.
Ryzen with 2400Mhz ram and Intel with 3733Mhz.
- Old iGPU tested with DDR4 2400, new one tested with DDR4 5GHz(or something).
Let's wait and see.
Simple fact is: Intel is currently selling a 10nm 4C/8T 25W mobile SoC that:
- on the CPU front performs like a desktop i7 7700 - way past anything AMD has shown to date,
- on the GPU front matches the best mobile AMD APU.
In other words: it's roughly equivalent to what AMD is rumored to show next year as Renoir (Zen2 + Vega).
Yes, some of the Gen12 GPU result stems from having faster RAM. So? Intel developed a solution that supports and benefits from the best DDR4 they could find.
When AMD gets an advantage from HBM2 I never see you trivializing that "it would be sh.t with DDR5". :-D
Basically it boils down to what you can afford (+availability) & what fits your need, in the mobile space I'd mostly prefer a better GPU but again it depends on the individual.
It's a very fresh CPU and just few laptops have been announced.
Dell has just 1 notebook with 1065G7 (new XPS 2in1) - estimated shipping in 10 days.
Sure, 1 laptop is not that great even at launch, but that's still more than the number of Ryzen 3000 desktops they offer. :p
In fact Lenovo and HP also announced a single laptop with IceLake-U. As with Dell, it's a premium convertible, so not really an important product.Yes, they start to sound like AMD in 2016. ;-)
Even just the TDP limit is a hard reality that they cant get around. More talk, no results is all this is. Another baby step on inferior node.
And if THIS is what they intend to market or fire up Xe with.... yeah... we'll talk again a decade from now.Exactly. Im still amazed they didnt pursue that 5775C further. Wonderful cpu.
Out of all PCs existing maybe 10% are used for gaming and maybe 1% for some kind of semi-conscious GPGPU - most of these have a graphics card anyway.
For the rest of users Intel HD is pretty much perfect.
They're increasing performance to support higher resolutions. That's it.
