The Zotac GeForce 9800 GTX AMP! Edition

The Zotac GeForce 9800 GTX AMP! Edition

Previously, we have seen Zotac's standard version in our coverage of the NVIDIA GeForce 9800 GTX. Appearance wise, the AMP! Edition is no different from that version with a similar Zotac sticker on its cooler. The difference lies entirely in the clock speeds. At 750MHz for its core, this Zotac is much higher than the 675MHz on the reference board. The stream processor clocks are also adjusted correspondingly, going from 1688MHz to 1890MHz. Memory clocks are increased to 2300MHz DDR from 2200MHz DDR on the stock versions. On paper, the impact of these changes should be much greater than the overclocked GeForce 9800 GTX we had seen from MSI.

Other aspects of the GeForce 9800 GTX remain the same - the noise and fan speed of the cooler appears to be similar and the features that you can expect from this SKU, like HybridPower, 3-way SLI support and GeForce 9 PureVideo enhancments are all present. Moving on from the performance aspect, even the bundled contents of the AMP! Edition is similar to Zotac's standard GeForce 9800 GTX. Unfortunately, this means that the rather poor Lost video game based on the hit television show remained in the package.

The contents of the Zotac GeForce 9800 GTX AMP! Edition are as follows:

  • DVI-to-VGA adapter
  • 2 x 6-pin Molex power adapter
  • 7-pin mini-DIN to Component dongle
  • S/PDIF cable
  • DVI-to-HDMI adapter
  • Driver CD
  • Quick installation guide
  • User manual
  • Lost: the Video Game (full version)


Test Setup

The same trusty system that we have been using for graphics testing is hauled out once again for this Zotac AMP! GeForce 9800 GTX. Consisting of an Intel Core 2 Duo E6700 (2.66GHz), an Intel D975XBX 'Bad Axe' motherboard and up to 2GB of low latency DDR2-800 memory from Kingston (dual channel mode), this system also had a Seagate 7200.7 SATA hard drive. We are still going with Windows XP Professional (with Service Pack 2) for now, hence we also updated it to DirectX 9.0c.

As the MSI N9800GTX-T2D512-OC is overclocked too, this card was a suitable comparison for the Zotac. We also included the performance of other major high-end SKUs from ATI and NVIDIA as reference. All the GeForce 9800 GTX cards were tested using ForceWare 174.74 while the slightly older GeForce 9800 GX2 was on 174.53. The remaining GeForce 8 cards were using 169.21. ATI's Radeon HD 3870 X2 had Catalyst 8.3 installed. The following benchmarks were tested using their built-in time demo or benchmarking tools:

  • Futuremark 3DMark06 (ver 110)
  • Company of Heroes (ver 1.3)
  • F.E.A.R (ver 1.0)
  • Supreme Commander (ver 3255)
  • Crysis (ver 1.1)
  • Unreal Tournament 3 (ver 1.1)
