Yea, I hit that VRAM wall really hard on HB2 a handful of times. It's the only thing that is keeping my 3070 from lasting several more years to 2028Even at 1080p, you can see some games hitting that 8GB vram wall:
Michael Larabel said:When taking the geometric mean of all the game tests that ran successfully on all of the graphics cards, the Intel Arc B580 on Linux came out to delivering 1.66x the performance of the prior generation Arc A580 graphics card. Or compared to the prior Arc A770 flagship, the Arc B580 was at 1.45x the performance. Overall though both the GeForce RTX 4060 and Radeon RX 7600 graphics cards were faster than the current Arc B580. It will be interesting to see though what more Battlemage/Xe2 graphics driver optimizations come to the open-source Linux drivers in the coming weeks.
Michael Larabel said:The Linux performance for the Alchemist-based Arc A580 and A770 were faster on Linux than Windows in part due to all of the OpenGL benchmarks and such, but for the new Arc B580 the better performance is on Windows 11 with Intel's latest Windows driver. It's nice that there is upstream open-source Intel graphics driver support for Battlemage on launch day, but there is still more room for better optimizing the Intel Xe2/Battlemage Linux graphics driver support. It should be interesting to re-visit this in the weeks/months ahead to see if the Intel open-source software engineers are able to close the gap for Battlemage.
Based on latest tests by hardware unboxed, performance drops in older systems even if the rebar is enabled. Common determinator seems to be cpu heavy game, so the drivers are not as optimized (or are optimized to newer cpus) as nVidia or AMD.Seems Intel memory management is still sub par, they still rely on Re-BAR to handle, as without it performance massively drops, this excludes Intel as a viable upgrade path for older systems.
As someone that recently finished HB2 on a 3070. Yes, that 8GB wall is hit hard from time to time. At times the game can also be a little buggy and lose VRAM somewhere in there like some sort of memory leak.
DF seems have better RT results that HUB - aside from Miles Morales.
One thing that caught my attention in the HUB review is that they actually left Physx ON for Metro Exodus, which should be killing performance on anything but Nvidia. DF used maxxed out RT and just disabled Physx:

What's more concerning is the frame time blips in several games (F1, Cyberpunk, Alan Wake, Spiderman). Those are deal breakers for me, hopefully they can be sorted. It further reinforces why reviews that only focus on average/1% lows are so inadequate, HUB didn't catch those stutters because they're not measuring it. Periodic brief stutters, even for a <1 min benchmark run, will not necessarily be detectable by 1% lows.
Even at 1080p, you can see some games hitting that 8GB vram wall:

I see possible bmg-g31 my only option from 3070ti. AMD RT performance is step backwards and 50 series prices will most likely out of my budget.I will have the a770 for awhile but it will be interesting to see if they release another faster version this generation. What would be great fun is if was like the old days where you could try unlocking cores and it was unknown whether you were getting an awesome deal or just a fine deal. If I'm honest though I think those days are gone and you would not attract many enthusiasts anyway.
3070ti is on 4060ti level which means that it will probably be 5060 level in half a year, and anything above that will be an option for an upgrade. Which means $400+ probably which is also where a faster BMG will likely be - give or take a hundred.I see possible bmg-g31 my only option from 3070ti.

So hoping the best.
