Fabio tested 50 games on the 8700G. FSR2/3/FG and XeSS. He is even using it for recording the gameplay. APUs have come a long way.
What a throw away sarcastic comment. dGPU advancement has little to do with IGP. Go find the fastest IGP from 2017 and compare it to the 8700G. You'll be able to make the same comment without the sarcasm.We have finally advanced from 7 years ago. Yay.
We need competition in whatever form it arrives. If some people playing esports or emulators pick an 8x00G instead of Intel CPU + NV GPU, that's good for AMD marketshare. 8x00G is a lot more viable than the previous 5x00G.We have finally advanced from 7 years ago.
It's coz the 6500XT is a PCIe x4 card electrically but physically x16. Four lanes on a PCIe 4 slot give it enough bandwidth to get the data it needs from system RAM to replenish its 4GB framebuffer with fresh data. On a PCIe 3 slot, 4 lanes gives it half the bandwidth of PCIe 4. So it keeps waiting for data to come and the idle cycles of the GPU drop fps.
RE4 Remake was the only game (that I saw in the video) that took advantage of the additional frame buffer capacity of 16GB. Every other game seemed to use just 200 or 300 MB more than the 8 GB setting.The other game engines were also weird in that using 16 GB frame buffer reduced the RAM consumption of the game by up to 2 GB but VRAM increased by only the aforementioned 0.2 to 0.3 GB. Weird and makes no sense.
I can't see how changing the memory allocation would make a difference. CPU and iGPU aren't NUMA, they're the same memory pool.
Not that I'm aware of. At boot there's probably a tiny amount of DRAM set aside by the BIOS which is part of "hardware reserved" in Resource Monitor, but we're talking about a few hundred megs at most.Related question - do recent iGPUs not have any kind of internal video RAM?
I counted two games that were near or over the 8GB threshold. My feeling is, if it's near the threshold, it's inevitably going to go over the threshold at some point during the game. The other thing to bear in mind is that these games are all running on the lowest graphics settings, so logically less video RAM would be needed.
Disclaimer for the following: I am not a game dev!
Other people have theorised that video RAM often doesn't get used for the immediate display of textures but for pre-caching textures that are soon to be needed. In such a scenario then at face value one might expect that GPUs with less video RAM then would see greater intermittent drops while the textures (that would have been cached in video RAM) get loaded in from system RAM, but maybe there's an additional layer of safeguards going on to try and ensure that the data still gets to where it needs to be (ie. "just in time" systems that say supermarkets run on to ensure that stock is optimal for normal situations), but with lower VRAM the "just in time" system is more vulnerable to frame rate drops when prediction inevitably doesn't work as well as it should, for example the game expects that the textures for the next area will be needed at such-and-such point but then the immediate action gets busy in a particular and less predictable way which then exposes anomalies such as texture pop or frame rate drops beyond excusable levels.
Related question - do recent iGPUs not have any kind of internal video RAM? I remember starting to adopt iGPUs for the average user in my PC builds at the point (I think it was AM3) that boards came with some soldered video RAM (I think it was referred to as the sideport RAM with AM3). For example, the ASUS M4A89GTD PRO had 128MB onboard video RAM for the ATI 4290 chip to use, and it also accessed UMA on the default settings.
The driver is doing some voodoo irrespective of the BIOS selected UMA size. The only thing that changes is system RAM utilization by the game. If the UMA is 16GB, VRAM increases and game's system RAM consumption goes down but the performance is almost unchanged.All memory access is shared through regular DRAM and the driver/Windows manage it dynamically.
Limited to just 16. The whole point of the setting is to dedicate a portion of system memory to integrated graphics; if the system could take it back, there would be no point in the setting.If you select 16G in BIOS and you have 32GB total system memory are you still able to utilize the full system memory outside gaming or are you limited to just 16?
Typical Prime. Gaming at 1440p. Well not really, I am using FSR performance but I started at 1440. LULZ!A small oc and 1440p.
