Most Expensive $4500 Quad GPU Setup from 2010 - ASUS ARES CrossFire

[@excess.subiefl0w]

Crysis 2 and 3 has amazing crossfire support. Few years ago I tried a radeon 7970 and 7990 in crossfire (3 gpus total) and it was getting 80-120fps at ultra settings 1440p with 95%+ scaling pretty amazing

[@bagelbytes69420]

Could you imagine a quad-SLI setup of 4090s? I dont even think you could cool that much wattage reasonably tbh. Its also insane that these halo level, dual-GPUs have a TGP of ~300w and now mid-high end cards eclipse that now. Wild stuff

[@12pandemon]

I remember seeing the Ares come out and being in awe at the thought of this exact scenario. I did see a lot of people do this but with the later 7990, which was an absolute behemoth in heat and size. I think I read a couple articles talking about the 7990's hitting well over 100c and outright crashing in some scenarios, but another commenter says they ran 7970 AND 7990 for triple GPU, which is something I never really thought about... might have to track some of these GPUs down, just to save them from being tossed away and lost to history. This period was amazing for AMD...

It's interesting that the average scales pretty well in some select games, but it seems that usually the 1% and 0.1% lows barely budge. Great work, and especially tenacity working through all those crashes to get this done though!

[@FullyBuffered]

Thanks man! Yeah the 1% and 0.1% lows barely changed, which was the same with the 4x 6870s. I’d love to know where the bottleneck is, but oh well.

[@4gbmeans4gb61]

Those 1% lows im guessing are from the CPU and RAM.

[@Kevin-fw9ks]

@@4gbmeans4gb61 I think that's probably the latency from one chip to another (or better, one chip to three others) plus driver management of memory

OH MAN THIS TAKES ME BACK! That arms race was hilarious! Back then it was really team red and team green trading blows. You could get close to the ares with 4x GTX470s, I ran mine with dangerden blocks and 360mm radiators from Swiftech. I believe bitspower made a full-cover waterblock for this one. As far as oc-ing these you needed a 1500W PSU with a fat single rail like the ones from OCZ and some wacky company made a PSU that was around 1800-2000w but had massive external PSUs or 350w individual PSUs that could go into a 5.25 drive bay and be triggered on by your main 24 pin with a Y connector. Wacky days and times.

[@SinaFarhat]

interesting times when sli/crossfire was a thing for a common person with a deep wallet. It somehow made sense when the programmer created support for a dual card setup in a game or a piece of software! I think the dual graphics card thing died out with the 10xx series graphics cards.

[@solarstrike33]

It was definitely on its way out by the time Pascal arrived - but that series was the death blow to it - as after that, the consensus became “just go for single cards”.

[@ishiddddd4783]

and a current GPU SLI or crossfire will go above 600W for the cards alone at the minimum

[@mclarenf1gtr99]

Cards just became good enough to play at 1080p and 1440p, that the cost to maintain a dual GPU graphics car was not worth anymore. In 2010 the goal was 1080p60 High settings with the enthusiast craving for 1440p, but with that last one, you needed more than an HD5870. The reason people didnt find use for a dual 780ti back in 2013 was because 4K tech was not big for gaming compared to 1440p and the 780ti itself was already 600€. There was the 2x760 but only good for the price, and there was the 2x295 which was the way AMD found to compete with 780ti, and people gone with 780ti because single GPU = no issues, and 780ti was well enough to play at 1440p. After that people stopped considering dual GPU for gaming.

Triple XFX 5870 crossfire setup back in 2011, had an Antech 1200w psu and an i7 920. It was a beast, then traded them for a 3 XFX R9 390 setup. I miss that pc.

[@InspectorExacto]

Another great video, Mr Buffered! I ran a crossfire setup for a short time some years ago, two HD 6950s. I originally had one and then a family member upgraded his setup and gave me his HD 6950. Heat and especially noise were a big issue so I ended up buying 2 Arctic Accellero GPU coolers (I forget which model but they were "silent" fanless models so they were oversize with farther spread apart fins but still not as big as today's top cards) and the system ran great for a while. But some months later one of the cards died (the HIS brand card that was given to me, the other was XFX) and ended my adventures with Crossfire. I forgot which games I was playing at the time (possibly Just Cause 2 was one) and it was awesome having the game run almost double the speed from using just one card!

Great video, beautiful cards I found that Catalyst 13.3 worked well for pushing 3/4way xfire Terascale setups on windows 7 (both HD 6K and 5K), though it is probably not the most stable for games.

It really is funny in a way to see four GPUs being trounced by a single one just 6 years newer. Comparably, a 1080 today is 6 years old and I dare say you will not find a single GPU today that is more than 4-6 times faster than one of those (issues with CF scaling not withstanding). Hell even a 3090 Ti is not much more than twice as fast iirc. Solid work and a fascinating product to look back on, especially as a previous 5870 owner.

I've played with crossfire a and SLI back in the days of the HD3870 and the GTX300.. wow i am showing my age there. Both were all ways twitchy, and were HUGELY impacted by drivers and games. More so crossfire than SLI. however SLI had many restrictions on it that crossfire did not. for instance SLI you needed the literal exact same card to enable it where as with Cross fire you could mix and match, even a 3850 could be paired to a 3870. However the extra hardware flexibility was pretty much canceled out by the instablity and inconsistent performance

Here in 2023, running a brand new AMD Ryzen 5 5600X and a lightly used RTX 2080 Super makes me glad things have come a long way since 2010 lol. And while my graphics card may already be "long-in-the-tooth" in 2023 for the newest titles, I am very happy with the performance in the hundreds of games I have up to Cyberpunk 2077 patch 2.0 and the expansion. Even back when this was THE thing, I never wanted a dual card setup. To me, it was just a waste unless the GPUs shared the same card. Even then, single GPU performance changed so fast that multi GPU setups stopped again. The only boost I would have liked is maybe using a second on card GPU for PhysX when that was still a huge thing, but now single GPUs just do it well by default it seems.
