That's cool, man. You're right that intel has only had 10 years of integrated graphics, but before that.... man it was the wild west of graphics cards. Intel, Matroxx, Geforce, ATi, 3dfx, Voodoo, and S3.

I hope those days come back because competition was awesome!

Intel graphics goes back to AGP days.

The problem is not if it can clock high. The problem is what that will do for power consumption when the design is scaled up to where it needs to be.

You can buy whatever, obviously. People bought the $1,000 GTX 690 after all, and I'm sure that card was a way worse deal than whatever Intel will put out.
5775c supports all DDR3 ram overclocks and runs concurrently to the edram, so you can add them and get about twice the bandwidth per eu at lower latency. At least in low ram MBs.

And I don't get where you think Intel is different than AMD on power consumption of the igpus. Maybe that potential big Navi will also be trash by your measure.

With a dgpu setup you would also be decoupled from the cpu, ringbus, power delivery, etc and be able to clock better. We should see more when they come out, but I don't think an Intel dgpu will clock ridiculously low. The igpu on my 4980hq does 1450-1500mhz and was released 2 months before Maxwell.

As far as a 512eu Xe sucking down a lot of juice, my main rig has a KW to spare for the gpu. I dare it to be thirsty.

rluker5 I got the impulse to show that Intel had the gpu clockspeed lead for a short time so I downloaded 3dmark and ran firestrike: https://www.3dmark.com/3dm/42585122
I kept the core speed low because my cooling and power delivery on that rig are terrible tbh and I was worried about the mobo during the combined test. I normally run it at 4ghz to keep the fan quiet. Cpu cooler also claims to be 65w, but really isn't.

Also [email protected] has same flops as [email protected] if you wanted to see the improvement with Broadwell igpu.

The DDR4 1030 has 16GB/s. The GDDR5 1030 has 48GB/s.

Two sticks of DDR4 3733, what the Ice Lake chip was tested at, can provide just shy of 60GB/s. I can confirm this as even my 3900X with dual channel 3600 gets 54GB/s reads.

Given a GDDR5 GT 1030 is still faster than an Ice lake chip, it should not be significantly starved with +25% max bandwidth.

skupples aren't must GPUs at the end of the day when it comes to high resolution high frames stuff?
