GeForce GTS 450 Slides Confirm Specs, Reveal Positioning

Chinese website IT168 posted slides leaked from the GeForce GTS 450 press presentation. The slides reveal the final specifications of the upcoming GPU, as well as show the market positioning. To begin with, the GTS 450, as mentioned in numerous occasions, has 192 CUDA cores, 1 GB of GDDR5 memory across a 128-bit wide memory interface, and clock speeds which include 783/1566/900 MHz (core/shader/memory); but the slides confirm that NVIDIA's reference design cooler looks nearly identical to the GeForce GTS 460, at least as far as the cooler shroud and fan goes. Other specifications confirmed are the TMU count: 32, four Polymorph engines (should translate into 16 ROPs), power input being just one 6-pin PCI-Express connector, and card max power draw of just 106W, nearly 2/3 that of the GTX 460.

NVIDIA is positioning this SKU to be the successor to the popular GeForce GTS 250, which held the sub-$200 and later sub-$160 markets for NVIDIA, for quite some time. Its target buyers are those which need a light on the pocket graphics card for LANParty rigs. The card can afford users smooth gameplay of the latest DirectX 11 titles at 1680x1050 with 4xAA. Unfortunately, what we're looking out for the most (price), isn't mentioned. Perhaps NVIDIA will stabilize the price of this SKU based on how it plays out against competing SKUs. Speaking of which, the ATI Radeon HD 5700 series is in this card's crosshair.

So G106 is half of a full G104. Does that mean that G108 will only have a 64 bit bus? Unless they get the memory controller faster, a gt 240 would be faster with gddr5 because it has twice the bus width.

Also for price I'm going to guess the 150 USD mark just because that is where the GTS 250 sits according to Newegg, before rebates, on the high end.

Likely 64-bit GDDR5, which isn't bad. It's on-par with 128-bit GDDR3.

It doesn't look to shabby, it might be good to have for PhysX or something.

Looks like a decent little card!

Problem is that GT 240 comes with GDDR5 as an option. Sure it doesn't do DX11, but unless the G108 brings something else to the take, it looks like it might go spec for spec with the 240 except on memory bandwidth. Reviews have shown that the GDDR3 version of the 240 is hampered by the lower bandwidth.

I guess I just don't see it as a good move.

According to the numbers of this news post, there is little room for comparison between the GT240 and this.

ROPs: GTS450 - 16, GT240 - 8.
SPs: GTS450 - 192, GT240 - 96.
TMU: GTS450 - 32, GT240 - 32.
Memory: 128-bit GDDR5, 128-bit GDDR3/5.

Edit: Sorry for the double post...

he's trying to draw a comparison to a different chip altogether, one that has not even surfaced yet.

GTX470/480 = GF100
GTX460 = GF104
GTS450 = GF106
GT440? = GF108

Correct Wolf

Its all based on the assumption that the G108 will be half of the G106 even though we don't know officially if the G106 is half of the G104.

As with these things, time will tell.

A worthy replacement for the G92 GTS 250. :)

gts 450 with 128bit isn't really that bad at price range of $150, though it may hurt the performance a bit when plays on crysis or any bandwidth starved game. otherwise it trumps in some directx 11 game that heavily require tessellation plus it has 192 cuda which far more than 5770's 800/5=160. overall, a good low budget card that's good to buy.
