Chinese website IT168 has leaked slides from the release presentation of
NVIDIA's upcoming GeForce GTS 450. While there are no major surprises, the
slides confirm several rumours. The reference design of the GeForce GTS 450's
body is identical to the reference GTX 460. It features 4 SM or 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 900 MHz mean a low bandwidth of 57.6
GB/s, well below the likes of the HD 5770 and predecessor GTS 250. The GTS
450 features 32 TMUs, and looks like 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.

GTS450的耗電表現還不錯，TDP為106瓦。然而，實際TDP和N家的數據可能會有所出入。
效能方面，GTS450預期處於Radeon HD5750和 HD5770之間。後者TDP為108瓦，前者則只有
86瓦。這三張卡都使用單6-pin PCI-e接頭。

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.

這次的賣點將會類似GTX460，即擁有優秀的性價比和相當好的超頻潛力。GTS450的零售
價格預計會比Radeon HD 5750略為便宜，為130美金，儘管比起後者多出了10%的效能。
下游廠商將會推出超頻版的GTS450，核心頻率將在900MHz以上，某些更可能上達1GHz。
想到原廠核心頻率只有783MHz，這樣的超頻潛力著實令人難以置信。公版GTS450將搭配
與公版GTX460相似的散熱器，提供足夠的冷卻能力：在預設風扇設定下，Furmark滿載
溫度只有72度C。

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.

整體來說，GTS450看起來相當強勢。有人暗指GTS450若有更高記憶體頻寬，或能更加強大
，但就目前情況來看，GTS450面對HD 5750仍具有極高的競爭力。然而，N家的問題在於
GTS450將無法對抗HD 5700系列太久，因為HD 6700系列將緊接著在一個月後發佈，也就是
10月12日。那時，GTS450的可能對手將是HD 6600系列。希望那時侯AMD能將HD 5700系列降
價至150美金以下。
