EVGA GeForce GTX 460 768MB

The cut-price GTX 460

TechRadar rating:

3.5 stars


Massive overclocking headroom; Great EVGA warranty


The 1GB version is only £20 more; And is faster especially with the overclock applied

EVGA GeForce GTX 460 768MB - overview

The brand new GeForce GTX 460 has turned up in two rather different flavours; the full version like Zotac's GTX 460 1GB and this the paired-down, slightly cut-price, 768MB version.

The GTX 460 is based on a new NVIDIA GPU and marks the first card sporting it.

We've gone into all the specifics of the GTX 460 architecture before, but basically it's based on the same GF 100 chip that keeps the GTX 480 going but with a more slimline approach.

There are fewer streaming microprocessors (SMs) but each of the new SMs carries more graphics cores, texture mapping units and other special function units.

The difference between the two spins of the GTX 460 though is totally down to the memory used. Both are running on GDDR5 but the 768MB version, as well as obviously having less memory, also suffers from a slower memory bus, fewer ROPs and less L2 cache.

EVGA's 768MB version of the GTX 460 is all about the reference design. The stock reference cooler is there and despite reports this GPU chiller wasn't up to it, we've found it doing its job quite admirably. Even with a hefty overclock attached to it.

You can see from the benchmarks the Zotac GTX 460 1GB edition is by far and away the fastest spin of this new card in any performance metric you care to throw at it.

EVGA's stock GTX 460 768MB though doesn't suffer too much by comparison, but for only a touted extra £20 for the larger memory pipes you'd be crazy not to save just that little bit longer for the better card.

EVGA GeForce GTX 460 768MB - verdict

EVGA geforce gtx 460 768mb

The lack of graphics memory grunt is most evident when you come to compare the tessellation-heavy Heaven 2.0 framerates. The Zotac GTX 460 comes in at a thoroughly respectable 13 frames per second, while the 768MB EVGA card struggles to even get up to 8 fps.

The issue with the 768MB version is the fact that it is running at the very limit of its graphics memory capabilities if you throw too much graphical work its way.

The cut-down 192bit memory bus is horrifically limiting at the higher resolutions and introduces a bit of a bottleneck at the lower end too.

The saving grace for the GTX 460 768MB cards though lies in the overclocking headroom available to it. If you avoid the high resolutions the card isn't specced to run at then a simple overclock will garner you the sort of framerates a stock-clocked 1GB card can manage.

I managed a hefty 175MHz boost to the core clockspeed and 200MHz on the memory clock.

At those speeds the EVGA GTX 460 768MB card was running quite happily under the reference cooler, still only hitting 57degreesC at full graphical load.

The fanspeed too stayed pretty constant, barely raising a whisper despite the heavy pixel-pushing grunt it was being expected to run.

The difficulty is the full-fat 1GB version of the card is reportedly only £20 more expensive than the cut-down model and delivers far superior results.

Sure the overclocking headroom in the 768MB card is immense, but so it is with the 1GB version too. The only chance the 768MB card has is with system integrators hoping to save a few quid on a rig build.

Though if there are supply shortages of the more memory-heavy GTX 460 then the 768MB card could stand a chance.

Which is more than can be said for the poor GTX 465. Poor thing…

We liked:

The massive overclocking headroom is a huge bonus for a sub-£200 card. EVGA's cards carry a full three year warranty so long as you register the unit at purchase, which is as good a reason as any to opt for EVGA's version over the others.

We disliked:

The fact the GTX 460 1GB card is only £20 more than this memory-hobbled version makes it tough to recommend the 768MB card.

Even with a standard 22" monitor the extra memory of the marginally more expensive card will still pay dividends.

Final word:

We can't see past the 1GB version of the GTX 460 when it comes to these cards. It's got the same huge headroom for overclocking and a far more capable specs list to boot.
