Nvidia GeForce GT 640 Review: Cramming Kepler Into GK107

Would like to see a GDDR5 version of this card. Be interesting to see the performance difference.
 
The DDR3 is without a doubt holding this card back. With a maximum memory bandwidth of just 28.5 GBps I'm surprised the card performed as well as it did. I'm just not sure what Nvidia was thinking. At 900MHz, GK107 would probably be capable of easily outperforming the GTS450. Was it cost savings, or perhaps a TDP limitation that made them choose DDR3 over GDDR5? If keeping below a 75W TDP was the problem, why not just use 1GB GDDR5 instead? Or even slightly lower the core clock if necessary? It probably still would've resulted in better performance.
 
Almost, nVidia, almost!
1. With the GT440 and GT240 offering it, I can't believe someone won't quickly release a GDDR5 version. With such an obvious improvement that would be, it does not bode well for yields or other costs that DDR3 had to be used, and the card still has a $100 initial price. Can it come down to where it needs to be without becoming a "loss-leader?"
2. Pretty decent settings were used in the charts. Considering how good most modern games look even cut down to "medium" settings, that HD7750 at or near the top of the charts makes people who insist you need a $300 graphics card to play games look silly. This makes me wonder all the more what this new card could do with GDDR5, assuming it's economically feasible. Of course if it isn't, then this card simply loses except in that niche [business] market that wants to run three monitors.
3. I think the word you were looking for in reference to the absence of a PCIE power connector is "eschew."
4. Interesting, I noted that the box image is of a Seraphim from the game Sacred 2. Might that [older] game be included with the card, is it meant to advertise that the card supports PhysX (which Sacred 2 will use), or is there a copyright lawsuit on the way?
 
If this card retails for the $100 this article is implying then its a really tough sell. The 7750 outperforms the 640 in every way except loaded power consumption and for a meager $10 more....
 
wow... is this card going to sell for $75?

I think nvidia doesn't want to kill amd outright and comes up with these really bad products.
 
The performance from this card is disappointing. So much for driving down the prices of the 7750s... I've been wanting to start using the 7750 in mid range builds because of the low power/single slot solution. But at 110ish its just not justified compared to the low priced 6850.
 
> ... The DVI, VGA, and HDMI outputs are capable of handling a trio of independent displays at the same time. And, unlike AMD's cards, you don't need a DisplayPort monitor or adapter to get the array up and running ... We tested triple-monitor Surround and had no trouble playing DiRT 3 at 5760x1080 using the lowest detail setting.

For such a low end video card, WOW... things really start get changing now...
 
So basically Nvidia FINALLY managed to give us 8800GT performance levels without the 6pin PCIe plug. I know the 8800GT was way ahead of its time, but we are talking 5+ years here aren't we? Its a good card, but way overpriced. If you have $100 you are much better off with the 7750.
 
needs to be $75 so the kids don't have to mow too many lawns to play D3.
 
At hardly 40 bucks more one could get a GTX460 and that has double the performance at least on paper vs this stupid card! Its sad what Nvidia is trying to pass off to customers!

Apples and oranges. 40 bucks is quite a bit, and also this card is a green card not only in the sense that it's made by nvidia. It uses a lot less power and generates a lot less heat, and it gets all the power it needs from the pci express slot itself.

It's still lackluster compared to amd's cards though.
 
Ouch, price for performance is pretty awful.

I managed to pick up a 7770 for $105. I know the 7750 can be had at the same price as this. So i'm not sure who would buy this when you can have so much more going AMD at $100. I really liked the Kepler architecture price/performance with the GTX 680/670 but this is dismal. AMD reigns king in the low end cards for now. I hope they release some killer cards with the upcoming GTX 650/660.
 
I know that the test system uses a very powerful processor in order to remove any possibility of a CPU bottleneck, allowing Tom's to compare different video cards against each other.

However, I don't understand how these results can tell you whether or not these cards will play your games at the resolution and settings you want. The likely buyers of this card are people who want to upgrade their 2-year old Dell without upgrading their power supply, and they're sure as hell not running an i7-3960X.

So, commenters... here's a good reason why people buy $300 video cards: they don't want to buy $1000 processors.
