NVIDIA’s GeForce GTS 450: Pushing Fermi In To The Mainstreamby Ryan Smith on September 13, 2010 12:02 AM EST

Meet the GTS 450
The reference GTS 450 takes a number of cues from the GTX 460, and without labeling on the card it’s actually quite easy to confuse with its bigger sibling. Top-side it uses the same concave shroud and partially-raised fan setup at the GTX 460, and only when you remove these cooling components do you find a simpler circular all-aluminum heatsink between the fan and the GF106 GPU.
Top: GTX 460. Bottom: GTS 450
Since this uses the same cooler design as the GTX 460, it has the same properties: it’s not a fully-exhausting design. The cooler on the reference GTS 450 exhausts towards both the front and the rear of the case, so some degree of case cooling is important. At only 106W TDP this shouldn’t be much of an issue, but there needs to be some airflow within the case.
Meanwhile the PCB and resulting card measure 8.25” long, the same as the GTX 460. This coincidentally is the same length as the reference Radeon HD 5770. The PCB houses pads for 12 GDDR5 memory chips with 6 pads on each the front and back, highlighting the fact that this card isn’t using a full GF106 GPU. With only a 106W TDP, only a single 6-pin PCIe power socket is required to power the card. As with the GTX 460, this socket is rear-facing.
The PCB itself is fairly unremarkable. As is the case with cheaper cards the components are a bit cheaper – you can see a ring-choke near the PCIe power socket. With the card’s fairly low TDP the MOSFETs serving as part of the VRM setup do not require any cooling with the breeze from the fan being enough to cool them at default voltages. The card comes equipped with 8 Samsung GDDR5 memory chips, rated for 4GHz operation. This means there’s a bit of headroom for RAM overclocking if the memory controller is willing to cooperate.
GTS 450 Reference Design PCB (EVGA)
The port configuration remains unchanged from the rest of the 400 series: 2 DVI ports and a mini-HDMI port. The GF106 GPU can only drive 2 displays just like the rest of the Fermi family, so for output options pick any 2 ports. Like the rest of the 400 series, the GTS 400 series is also surround vision capable, so if you have a second card you can SLI them together to gain an additional display output for triple-monitor usage. As this is a lower-end product 3D Vision Surround is not supported due to the lack of performance, but NVIDIA Surround (2D) is supported.
Finally, as was the case with the GTX 460 launch, a number of partners will be launching their own designs today, which we are covering in our companion article that focuses on them. All of these cards are using the NVIDIA reference design or what appears to be a minor variation of it; the big difference on the hardware side of things is the cooler used and bracing methods.

just4U - Monday, September 13, 2010 - linkHere in Canada I haven't really seen any 5850's priced under 300 yet and most are up in the 330 range.. The 1G 460 sit's in the 220-240 (no price drops for us) so it's a tempting alternative for many (I think)
I also believe the 5850 will be a $200 card sometime in the near future. It's been selling way above it's suggested retail price (at launch) and when that happens it will be harder to consider the 460 as a viable alternative. I can't see it being sold at $150 (for the 1G variants) any time soon... so only fan's of Nvidia would consider it if it's priced in the 5850s range.
jabber - Monday, September 13, 2010 - linkBig thing is...who actually bought a 5830?
When it came out everyone said it was a pointless card so big whoop, Nvidia's 460 beats a card that should never have been released in the first place.
Bit like saying "our car out performed the Ford Edsel!"
If you want middle of the road performance you get a 5770, if you want a better boost you get the 5850.
just4U - Monday, September 13, 2010 - linkIt was only a pointless card because of it's price... Originally it should have been alot cheaper but supply and demand has inflated the prices of most of Amd's 5X lineup. Sitting near a $100 more then the 5770 is what made it a hard sell.
erple2 - Wednesday, September 15, 2010 - linkSure it did - the 768MB version fo the 460 now gave you 5830 performance for > 10% less money. To me, that makes it sound like the 5830 was now "obsoleted" by the 460 series. The 1 GB card was significantly faster at the same price point, and the 768 MB version was just as fast, but significantly cheaper. Both using less power, noise and heat.
Isn't that essentially what defines "obsoletes"?
SandmanWN - Monday, September 13, 2010 - linkThroughout the entire test suite the 5850 is within 4-6 frames of the 470. In two it makes it to 8 and 10 frames more. Given you need an extra 100W's on your power supply and the additional cost associated with that just to get that tiny fraction of output, the statement seems fanboyish. AT should be better than this.
just4U - Monday, September 13, 2010 - linkWhat does the 470 have to do with this? Most of us all agree that the 465/470/480 are all heat scores with insane power draws.. the 460 addressed that and came in at a price point that hit a sweet spot.. bringing alot of the 470/480's strengths and none of it's weaknesses to the table. Only real complaint I've seen for the 460 is the mini hdmi.
IceDread - Tuesday, September 14, 2010 - linkYou are missing my point.
By saying "and it struck beautifully" implies that you are cheering for the nvidia team. It would be a different thing if he wrote "and it struck hard" or something like that.
adonn78 - Monday, September 13, 2010 - linkI read another review, damn my cheating heart. That stated the SLI scalling ont hese cards were impressive. You got 2 GTS 450 cards but no SLI?
Stuka87 - Monday, September 13, 2010 - linkEr, every single benchmark shows the GTS-450 SLI scores. They are marked in green (like the regular GTS-450).
marraco - Monday, September 13, 2010 - linkOther web sites show that the 450 is slower than the 250.
It's strange when the 250 has 128 shaders, and the 450 has 192.... and the 450 has DDR5 vs DDR3 in the 250.
It looks like the texture units bottleneck this design.
Even more strange is that I could not find the 250 on this article charts.
I don't see the 450 as price competitive with the radeons, except as SLI setup. It would be more valuable if 3-SLI way were allowed, and I guess that is not the case, because the photos shown only a single SLI connector.
The SLI setups are unbeatable against the radeons price/performance. Maybe nVidia should design cheap, energy-efficient chips so a card manufacturer can pack 10 video chips on a single card.
