EVGA GTX 580 3GB Classified Graphics Card

The GTX 580 classified one of the fastest single Fermi based cards ever made this card comes equipped with 512 cuda cores and 855 megahertz core clock and a whopping three gigabytes of fast gddr5.

Now all of us comes housed in a no-nonsense all-black design that screams overclocked me this classified was released in October of 2011 which is almost a full year after the release of the GTX 580 it was priced at 600 USD which is quite a bit to stomach at the time.

But it’s obvious as card cater to the overclocker and all of us upon release EVGA announced a 1.5 gigabyte and a 3 gigabyte version of the card as well as the ultra version now that came with a core clock of 900 megahertz out of the box.

Aside from those differences all the 580 Classifieds were essentially identical so you might ask yourself what features does this classified have over the reference GTX 580 well I’m glad I asked first we have a BIOS which now put the card in overclock mode which allows for voltage adjustment.

It disables over current and thermal protection as well next we have evbot support the evbot allows for adjustment of voltages changes in PWM frequency and again disables OCP without any software now voltage measurement points are included this will allow accurate voltage readings directly from your graphics card which is more accurate than software.

Now this beast also has 14 power phases and three memory phases now these are housed under a robust memory MOSFET plate and above the vapor chamber heatsink resides a monster 80 millimeter blower fan it’s loud but it does get the job done the classified also has support for three and four Way SLI.

The classifieds PCB is about an inch taller than the reference PCB and it comes in at 11 inches long now the extra inch allows for all the power phasers to fit on board and it gives more heatsink surface area as some of the heat produced does get blown through a top vent as shown here at the top of the card you can see one not two but three peg connectors.

Power Draw

We have to a pin and one six pin if you were to add all of these up per the ATX spec this could draw up to 450 watts but with enough love and voltage you can blow well past that spec next the pet connectors you can see three connectors for checking the card voltages with a multimeter.

Benchmarking of card

We can check the vcore the PLL and the memory voltages connectivity options are only two DVI ports but there’s also a connector for the EVGA evbot which unfortunately I don’t have since we’re overclocking on air it’s not really needed all right well that pretty much wraps up the features of the card but what about the questions you all have right about now.

Some like how well does a 580 classified hold up in games today how well does it overclock how much power does it draw but most importantly is Fermi dead now like it’s driver support these are all great questions.

I needed to with a current version of MSI Afterburner along with EVGA ZV tune tool now this card has a base clock of 855 megahertz and a shader clock of 1710 with a memory clock of 2000 for now some of the three gigabyte classified models have slightly higher memory clocks unfortunately this one does not.

I can’t adjust the core voltage with afterburner regardless of what setting is used so this is where the Eevee tune tool comes into play you first need to make sure the card has the overclock BIOS set and then fire up Eevee tune and adjust the NV VDD slider

Now I tested a number of voltages but I ended up settling on 1.3 volts at this voltage I was able to achieve one gigahertz on the core.

I had to make the fan at 100% and at this speed it’s just really loud a couple of you were interested.

Games Performance On Card

Here’s a quick look on our test system that are used for all of our benchmark runs it’s now time to test performance in ten modern games the first game up is Rainbow six siege and at 1080p with the medium preset the stock clock classy produce 50 frames per second now after dialing in our overclocked performance increased 14% to 57%.

Now you can see VRAM usage stayed below two gigabytes during the built-in benchmark and during our gameplay capture a frame times remain consistent and exceptional during our entire capture.

I also wanted to note the green line on the graph represents the stock run and the magenta line represents the overclocked let’s jump over to a newer title destiny.

We tested a 1080p use in the medium preset and stock clocks we averaged 56 frames per second overclocked.

The number grew at 12% to 63 now this game played extremely well but we did run into a couple frame time issues and stock clock speeds now this was tested many times and was repeatable every time as soon as we overclocked the card these issues all disappeared for tonight is the next game up.

I’ll be quite honest performance here quite surprised me and we tested at 1080p using the high preset with SMA a and at stock we averaged 49 frames per second overclocked the number rose 14% to 56 now VRAM usage hovered in the 2.6 gigabyte range and frame times.

Were extremely tight now keep in mind since Fermi GPUs do not support Falken this was all OpenGL now tested many Fermi cards in this game and they don’t even come close to this cards performance.

I truly believe the high core count high clocks and extra vrm really helped this card soar now on to the oldest game in our test suite GTA 5 this game is still very popular and that’s why I always try to include it in my tests now Fermi GPUs are known to rip through this game so this card is certainly no exception now using all very high settings and FXAA at 1080p.

We average 61 frames per second and after diamond in the overclock we saw that number jump up 13 percent to 69 VRAM usage look good only sitting in the 2.5 gigabytes much of the time frame times also look great but we did experience some slight micro stutter.

But the milliseconds spread is so low it can’t be seen with your console eyes PUBG has taken a bit of a backseat to fortnight lately but it’s still a very popular fugly game.

I chose 1080 P he’s in the medium preset and we averaged 48 frames per second now while it doesn’t seem that impressive for affirming base card it really is having three gigabytes of vram.

I did test this multiple times and it remained the same through all my results regardless it’s still really amazing to see this type of performance in a newer game with this Fermi powerhouse well that wraps up our game testing so let’s jump into some synthetics now first up we have Unigine super position using the 1080p medium setting stock we scored 39 to 48.

After overclocking that never jumped up to 45 38 that’s nearly a 15 percent increase in performance which is great scaling now let’s move on to an older unit in benchmark Unigine valley and here we chose the extreme HD preset and got a score of 1501 overclock the number rose 12% to 1692 that’s a pretty good result in my opinion.

And the last synthetic tests we have today is 3d mark fire strike Stan now the stock classi obtained a cheap hew score of 50 $1.99 after overclocking it rose to 59 64 which is pretty good for those of you with a 750ti maybe a GTX 760 or a 960 or an comparable AMD card.

Now I measured stock and overclocked power consumption on two separate systems I first used my 2600 K overclocked testbed and then I use my 5820k overclocked testbed now looking at the bottom you can see the 2600 case system pulled 339 watts from the wall.

The 5820k system pulled 424 now after we applied our 1.3 volts the 2600 K system pulled 476 watts at the wall and the 5820k pulled 567 now that’s quite the difference as a 5820k system is a bit piggish and these numbers are all measured at the wall with a watt meter and keep in mind if the 580 was water-cooled power consumption would definitely drop a little bit.

I can’t imagine it would keep pace with this card and there’s this test suite so keep in mind in a lot of these games I still had vram left in the table so we could always increase the texture detail as well and while performance numbers and everything looks great there is an Achilles heel for the king of Fermi’s and that is Ubisoft games I tested.

Only Far Cry 5 in my test suite but I also fired up Assassin’s Creed origins and Ghost Recon wildlands and they both ran like absolute dog crap on top of the artifacts and glitches that we experienced in both games performance was in the 20 FPS range on low settings at 1080p in both.
