That 16GB 580 sounds cool for memory-constrained scenarios, but it'd obviously make more sense to get a more powerful card entirely.
Yep, Dawid already made a video comparing an original RX580 8gb vs the circumcised RX580 with 16gb. Out of all the games he tested there's only 1 that utilizes that 16gb memory but it's below 10fps! lmao.
My previous GPU was a 4GB RX580 and it definitely was VRAM limited. 8GB is probably the sweet spot for that card (I might've kept mine longer if it had 8GB), but, at least for gaming, I don't really see a point in having 16GB on a card with that level of performance
Heh, caught me off guard with that description.
That video sounds about right. The place that more VRAM would be useful in is with compute, such as machine learning and video and photo editing, CAD, etc. I was doing image upscaling for the frames of a video a while ago, and it's easy to fill up all 8GB of VRAM by upscaling enough images at once.
But the 580 is old by now, so it wouldn't make sense to get a 16GB one for that either.
It wouldnt make much sense at all but Id like to have one. Really wouldnt mind seeing a Vega VII modded like this with more ram or even a vega 56 or 64. Those can be setup to sip the power and remain very capable for compute.
Im actually loving what the crypto crash has been doing. So many cool options for a decent price. At least where I live.
That's fair. I'd love to have one for a collection as well. Crypto has indeed churned out some cool mods of pre-existing cards. The machine learning boom might also incentivize more mods of this nature, since that benefits from VRAM just as crypto did.
Vega uses HBM memory that is on the package, unlike GDDR which just sits on the PCB. That mod would be much more complicated if not outright impossible.
Ah didnt think of that was just thinking about how the frontier edition is the same exact thing just with more ram and modified firmware and how there were even larger stacks of hbm2 memory available so the possibility of a vega 64 with even more ram seemed exciting. Properly tuned with amdmemorytweak or even just a good undervolt and they can be very efficient.
Even the 5500xt 8gb could provide some decent compute power with a bit of tuning or going in with more power tool and really unlocking the memory.
Would be awesome to have total control over your cards like that. Like oh I want this gpu but with this much ram at this speed using only this much power and easily making that a reality.
Idk im really into this stuff and have several of the chinese motherboards with old chipsets and modded bioses on them too. Kinda cool having a cheap unlocked xeon system that for the most part is totally usable. Before that years back was modding asus made hp motherboards to overclock xeons and running mobile amd chips in dual cpu systems to oc.
Could keep a lot of stuff out of the dumps and in use this way which I think is a good thing. Hopefully they figure this out on better cards the 580 is pretty weak
All Vega support HBCC. You can just turn HBCC on and tell games you have more VRAM, which does provide a performance boost in games that actually need it. If you don't need it, it does nothing.
I remember that made some benchmarks really happy. Havent tried it in years seemed pretty hit or miss, wonder if theres any reason to try it out again. Seemed to benefit the lows more than anything.
Idk Ill probably keep using these cards for quite a while. The VII is a beast for compute 64 and 56 both good too and still able to game with them at more than acceptable frame rates and resolutions. Idk I guess what I considered acceptable might not be the norm though I was watching videos about various handhelds for my son who wants to buy one and the people in them were calling 52 fps unplayable.
There's only two I'd recommend, Steam Deck, and AYN Odin 2. The windows handhelds are worthless battery hogs, and a terrible OS for handheld. The android handhelds are garbage with anything less than snapdragon. There's some acceptable dimensity 1200 ones, but the Odin 2 is a gen2 and cheaper. I'm not even sure if Steam Deck is worth OLED, no hall effect or freesync, and the power savings are cheating. The original Deck used more power than the limit, while OLED uses the exact limit, so they're lying through omission. OLED is also a cost saving edition with some things made cheaper, while "improved" in other ways, so it's not a total win, and the power savings are a numbers game, but you DO get a bigger battery, which was rather small on the original. I found 45 FPS to be a reasonable compromise on the original. Meanwhile, there's linux support on ARM, with x86 emulation, which if done right, could be a steam deck on ARM. That said, the actual Deck has superior support and controls, can slap on a battery pack. Also, if you go tablet, there's a tablet that does 3D like the 3DS. Lots of choices, not like the old days of nothing good. Nintendo has hacked switch mods, switch 2 could come out 2024, while you can emulate switch on the odin2. shrug
I mean for a local llama setup or stable diffusion the 580 could be nice.
But would have to use OpenVINO with an OpenCL backend instead of using ROCM as I think these have been removed from ROCM.
… unless there is a good Vulkan backend these days.
Dawid has great videos. I love that type of content where tech people test random "weird" hardware.
Maybe it makes some sense in the AI arena. But I tend to agree that going with a better GPU is the way to go.
As for using RTX 3080,.... for AI. I think Chinese have issues with sanctions.
Would've been good budget option for hobby AI if it wasn't about 200x slower than Intel A770 for SD/LLMs.
I agree. I did deep fakes years ago with my 580, and having 16GB of VRAM would've been great for dealing with larger models and whatnot, but it's past its prime at this point. Most budget cards today would be faster than it in compute, so that would be the reasonable option compared to the novelty of a 16GB 580.
Also, is the A770 really 200x faster in SD/LLMs or is that an exaggeration? I'm asking out of curiosity. I did some SD with DirectML and it was certainly slow, around 2 minutes for a set of images.
Probably a bit of an exaggeration but not too much. Intel released OpenVINO, making the A770 about 7x faster than the RX 6700.
That sounds about right. Nvidia and Intel seem to have better computer API support than AMD, so it doesn't surprise me that the A770 performs much better with OpenVINO compared to the 6700. Alchemist is generally powerful in computer anyways, so that helps too.
The power draw was already a lot with a 3080 12gb. I traded in for a 4070ti (on sale for $800 at the time for a higher end AIB) and cut my overall PC power consumption by 30%-50%! Since I pay the electric bill, this feels good. And I'm getting more frames. The 12g has been more than adequate so far and handles 4k well enough in any application so far. ☺️
Makes sense. The energy usage probably wouldn't be noticeable over the course of a year for normal usage, but that's still a decent trade. A more efficient card that's also faster. Pretty good.
Yeah you really need like at least 3070 performance levels to properly use more than 8gb Vram without crippled performance. And that's already more than 100% faster in most modern games. So yeah while the 580 was a very decent card for its time it obviously aged and now is only low end with horrible efficiency compared to anything modern.
Agreed.
