Testing:

Testing of this trio of NVIDIAs latest assault on ATI's product stack the GTS 450 will consist of running the cards through the OverclockersClub.com suite of games and synthetic benchmarks. This will test the performance against many popular competitors. Comparisons will be made to cards of equal and greater capabilities to show where it falls on the performance ladder. The games used are some of today's newest and most popular titles to give you an idea on how the cards perform relative to each other. The system specifications will remain the same throughout the testing. No adjustment will be made to the respective control panels during the testing with the exception of the 3DMark Vantage testing where PhysX will be disabled in the NVIDIA control panel. I will test the card at stock speeds, then overclocked in order to see how much additional performance is available and to determine if it can run with the current fastest single GPU cards on the market. The drivers used in this test will be the 10.7 Catalyst drivers for ATI and 258.96 Forceware drivers from NVIDIA for the GTX 480, 470, 465 and GTX 460. THE GTS 450 and prior generation GTS 250 will be tested with the latest 260 series driver being introduced with this product lineup. Tests will be conducted at both stock and overclocked settings to gauge performance when an increase in clock speed is applied.

Overclocking:

Overclocked settings:

NVIDIA GTS 450  952/1092Mhz

NVIDIA says that this little gem is built for overclocking, normally you take that with a grain of salt but the GTS 450 has some legs on it and ended up with a pretty stout overclock that resulted in some substantial performance increases across the board. The base clock speeds on the reference samples were 783/902Mhz. By using the latest version of MSI's Afterburner video card overclocking utility I was able to increase these clock speeds up to 952/1092Mhz. Since there are two of the reference cards it would not seem right if only one card would run these numbers but both the cards would run at this level when run in SLI mode. To get one card this nice is a good thing but to have two do this is a good indication that the series may allow for this kind of clock increase with the GF 106 based cards. For 3Dmark testing only 980/2290Mhz were stable enough for the lower resolutions but not quite stable enough to pull through the whole suite. To get to the stable clock speeds I did need tickle the voltage up to 1150mv and increase the fan speed to keep the card(s) running stable through the whole gaming test suite. The end results are an increase of 169Mhz or 21+% on the core and shaders with an increase of 190Mhz or 20+% on the GDDR5 memory. Both of these increases contribute to a substantial increase in performance across the board.

 

 

ASUS ENGTS450 TOP  975/1090Mhz

When it came down to overclocking the ASUS ENGTS450 TOP, there was not too much that I was expecting seeing that it was factory overclocked at quite a high speed. To my surprise I was able to get the core clocked all the way up to 975MHz which is only 50MHz higher than stock speeds, however it is 192MHz higher than the standard reference GPU clock speed. I was also able to overclock the memory of the card to a whopping 2180MHz, which is 180MHz higher than the stock speeds for the ASUS ENGTS450 TOP. I did have to increase the core voltage a tad bit to make the card stable, however it was only by 37mv, a small price to pay for an increase of almost 25% on the core speeds.

 

Inno 3D GTS 450   955/1060Mhz

The Inno3D was very simple to overclock, without voltage it moved right up to 965 MHz where it was unstable, backing off to 955 MHz proved fully stable without any voltage increase. Using MSI Afterburner 2.0.0 the voltage was able to be increased and this allowed the GTS 450 to operate past 1 GHz speeds, not an easy feat for any video card. The memory was set for 1060 MHz but had some head room left, the modules were getting pretty warm so that speed was good enough. Temperatures were never a problem with this being one of the coolest operating temperature air cooling cards I've tested.

 

Maximum Clock Speeds:

MSI's Kombuster utility was used to test stability and to put a constant load on the GPU for the purposes of testing maximum power draw and temperatures. The stability test was used to find a range of settings that are stable through a 15 minute run at 1920x1200 8xAA. The reported clock speeds are those that proved stable over a 15 minute test at 1920 x 1200, 8x AA and the run through the benchmarks suite.

 

 

  • Gaming Tests:
  1. Far Cry 2
  2. Metro 2033
  3. Crysis Warhead
  4. Call of Duty Modern Warfare 2
  5. Just Cause 2
  6. Unigine Heaven Benchmark 2.0
  7. Batman: Arkham Asylum
  8. Resident Evil 5
  9. 3DMark 06 Professional
  10. 3DMark Vantage
  • Usage:
  1. Temperature
  2. Power Consumption

 

The trio of GTS 450's shows that they really do have some serious overclocking ability. This bump in clock speed should help the performance delivered in game. Something that should show in the following benchmarks.
