Chinese website IT168 has leaked slides from the release presentation ofNVIDIA's upcoming GeForce GTS 450. While there are no major surprises,the slides confirm several rumours. The reference design of the GeForceGTS 450's body is identical to the reference GTX 460. It features 4 SMor PolyMorph Engines with 48 SP or CUDA Cores each (much like GF104,unlike GF100), for a total of 192 SP. The core is clocked at 783 MHz,with the shaders at 1566 MHz. 1GB 128-bit GDDR5 memory clocked at 900MHz mean a low bandwidth of 57.6 GB/s, well below the likes of the HD5770 and predecessor GTS 250. The GTS 450 features 32 TMUs, and lookslike a fully enabled GF106 part. In essence, GF106 is GF104 cut in half.
The GTS 450's power consumption is decent, with TDP listed at 106W. However, we have seen actual TDP and NVIDIA's figures vary in the past. Performance wise, the GTS 450 is expected to be somewhere between the Radeon HD 5750 and Radeon HD 5770. The HD 5770 has a near identical TDP of 108W, but the HD 5750 consumes only 86W. All three cards, as expected, use a single 6-pin PCIe connector.
NVIDIA's key selling points will be similar to the GTX 460 - excellent price/performance and high overclocking potential. Expected to retail at $130, the GeForce GTS 450 is slightly cheaper than the Radeon HD 5750, despite performing approximately 10% better. Heavily factory overclocked versions will be available, upto 900+ MHz. In fact, the some GTS 450 may hit 1 GHz. From a stock speed of 783 MHz, this is incredible overclocking potential. Sporting a GTX 460-like cooler, the GTS 450 provides ample cooling performance, with Furmark load temperatures only 72C at default fan settings.
Overall, the GeForce GTS 450 is looking like a strong product. One might suggest that the card could do better with more memory bandwidth, but as it stands, it is still extremely competitive against the Radeon HD 5750. However, the problem for NVIDIA is that the GTS 450 won't be competing against the HD 5700 series for long. Being 11 months late means AMD's Radeon HD 6700 series is set to release in one month's time, on October 12th. At the same time, the GTS 450's likely direct competitor will be the Radeon HD 6600 series, though we are not sure when it will release. Till then, we hope AMD drops the price for the Radeon HD 5700 series to finally ignite some life into the mainstream ~$150 segment.
