The Inno3D GTX460 was used in the following test system:
- Mainboard Asus P5Q Pro
- CPU Intel Core2Duo E8400 @ 4GHz
- GFX On Review
- CPU Cooling ProLimaTech Megahalems
- Memory 6GB DDR2 4-4-4-12 (Corsair & G.Skill)
- Disks 2 x Samsung F3 500GB in RAID0, 1TB Samsung F1
- DVD burner - Stock DVDRW
- Case InWin Maelstrom
- PSU OCZ Modxtreme 600w
- On Review Inno3D GTX460
Installation was easy as pie - especially since its quite a small card in comparison to some - at only 8.2" long - it should fit in the majority of micro-atx/atx cases. Noise wise, I could not hear this cards fan above the rest of my system fans - when the card is not under load (i.e. during normal 2D applications) the fan is very quite!
Rumours had it that this card may overclock to near GTX480 speeds well, Ive got some good news I managed to get it past GTX480 speeds! The overclocking also had a positive effect on synthetic benchmark & real world gaming results, however, we can't expect it to be able to match GTX480 performance - after all, this is a mid-range card.
I started by upping the core clock (and linked to that is the shader clock at a 2:1 ratio) in 25mhz increments. I found that my system froze up at 810 MHz, so put the clock down to a stable 795mhz a massive 100mhz overclock (reflected by the shader clock at 1590mhz). I then moved onto the ram, stepping it up in 25mhz increments eventually taking it from the stock 1800mhz to a whopping 2080mhz. This is obviously a substantial gain, and it is reflected in the benchmark results.
Whilst overclocked, I set the fan to maximum - at this speed it was noticable, however it wasn't obtrusive, and ensured that the card stayed at or below 50Ίc on a hot 23Ίc summers day.
Frames per second were recorded using the games built in benchmark (where available) or from a period of playing the game while recording the fps with fraps. The latest drivers at time of testing were used: nVidia Driver 258.69, and Catalyst 10.6.
The driver provided from Inno3D for this pre-release card is 258.56
Cards used for comparison:
- Inno3D GTX275 iChill edition (pre-overclocked)
- ATi HD4870 Watercooled (at stock clocks)
- Asus 9600GT 512MB (at stock clocks)
Whenever possible, benchmarks were ran at 1920x1080 (1080p my monitors max resolution) and additionally at 1280 x 1024. Also, all games were fully updated before benchmarking
Since only the GTX460 supported DX11, I ran Dirt 2 in DX10 mode for all cards. Settings used were a high as they would go, with 8x MSAA.
Surprisingly, my GTX275 still pulls its weight in many games in this case, managing a consistent 10 fps more on average than the GTX460. However, the GTX 460 clearly beats the 9600GT in this benchmark.
Strangely, again the GTX460 is beaten in this benchmark I am particularly surprised given the overclocked result is actually lower than the stock clock result. I imagine this will be fixed with an update from either the devs behind DIRT 2 or in a future/release day driver from nVidia. Out of interest, I tried the GTX460 in DIRT 2 at DX11 settings, and we can see that it barely affects the frame rate unlike the difference between DX9 & DX10, DX11 seems to be much better optimised, and the GTX460 takes the additional special effects in its stride. And in my opinion, it provides a definitely noticeable difference in image quality.
Batman: Arkham Asylum
The second game in our benchmark suite is Batman: Arkham Asylum. As MSAA only works on nVidia cards with this benchmark, it was disabled during this benchmark run. Otherwise, all settings were set to max and the benchmark was run at 1920x1080 and 1280x1024.
We can see here that the GTX 460 is king of the hill. This may be due to Batman Dark Asylum being a newer game, and therefore better suited to the GTX400 series cards, or maybe better driver optimisations from nVidia either way, a clear win by the GTX 460.
It is also clear here how much of a benefit a simple bit of overclocking will make with this card a jump in 5 fps on the minimum frame rate, and a jump of 10 fps on the average.
Again, the GTX 460 shows its strength and again the benefits of overclocking it. This is a chip which scales well with clock speeds! Id be interested to see additional performance gained from overclocking the 1GB version, as it has a wider memory bus which leaves greater potential for overclocking.
This test also demonstrates how far nVidia have come in terms of optimisation compared to ATi with regard to physx and DX10. The ATi 4870 was a king only 12-18months ago, and yet here, we can see that even the 9600GT beats it!
Resident Evil 5:
Is in our benchmarks as it is a popular DX10 game, and includes its own benchmark which helps to keep things consistent.
Strangely, almost all the results are quite similar which I imagine indicates a possible bottleneck on my system (CPU since its only dual-core?). Either way, for some bizarre reason, the HD4870 wins this benchmark, followed closely by the GTX 460 OC, GTX275 and GTX 460 in respective order.
Similar results are seen in the 1080p benchmark the limit seems to be my CPU? However, an average FPS of around 60 is certainly enough for even the most criticizing of enthusiasts!
Sadly, this benchmark does not include minimum FPS.
