[citation][nom]wmac[/nom]I am stoned that what have they done to GT640 that with 2 times the cores it is so much slower than GTS450!!! How can this be? Is that just because of the DDR3 RAM?I was hoping to upgrade my GTS450 and save 50% power but it seems it won't happen.[/citation]
It's a completely different architecture, you cannot compare this number...
[citation][nom]CaedenV[/nom]The only thing you need to add to the picture for HTPC is if it will play blue ray... and every dedicated GPU made in the last 5-7 years can play blue ray back just fine, and if you have a current gen CPU then the onboard GPU has more than enough power for video playback.In other words; It is a moot point. If anything can play back video, but other cards that are merely $5 more can knock the socks off this product in other segments, then there is no point in even looking at the 640 until the price comes down a bit. Besides, until there is a fanless passive cooler for the product then there is little point in adding it to an HTPC.[/citation]
Many use their HTPC for casual gaming.

[citation][nom]SinisterSalad[/nom]If you figure out a way to run two of the 640s or 7750s, let us know. Going to be tricky with no bridge for them.[/citation]
You don't need a CF bridge to do CF. There are many people who have done 7750 CF. CF, unlike SLI (if I remember correctly), is software. The bridge is just an extra connection so that the cards can talk to each other without their communication having to go through the PCIe bus. Lower end cards such as the 7750 have no trouble using the PCIe bus (probably because they don't need as much bandwidth and/or as low latency of a connection). Heck, you could get an X79 board or a Z77 board with a PLX chip and fire up a quadfire 7750 system if you wanted to, although driver support for it might be more lacking than officially supported configurations.

yea the 640 is just a cheap card for newbs that want to brag about having a kepler GPU. expect to see these in every crappy HP computer soon.

Cheap? It's in the Radeon 6670's performance range, despite being in the Radeon 7750's price range. That's a poor price there, especially for a 128 bit DDR3 card.

Radeon 7770 OC is nearing $100, it probably go lower in another 6 months in the mid b4 AMD plan to ship 8000 series, Nvidia step up the 7770 OC competitor now. or I am jumping to AMD.
I have been using Nvidia Card since TNT64,Geforce2MX, Geforce3Ti200, Ti4200, 6600GT, 9800GT, GTX570. You do not want me to start using AMD.

What does the 7770 have to do with you? Your GTX 570 is a lot faster than the 7770, so the 7770 would be a downgrade for you. Theoretically, you could sell your GTX 570 and get a Radeon 7870 or go up to a GTX 670 and either of those would be an upgrade, but the 7770 hardly seems relevant for you unless you were considering 7770 2GB Crossfire which would beat the GTX 570 substantially, but would be a dual GPU configuration.

[citation][nom]Rockdpm[/nom]"Perfect for a HTPC" But i wouldn't consider it a gaming graphics card...[/citation]
The Radeon 6450 or even Intel's own HD 4000 are both more than enough for an HTPC. I would not call the 640 GT perfect for an HTPC at all.

7750s can be configured without the need for a bridge as the PCIe slots have enough bandwidth to support a 2-way crossfire. I am unaware if these 640s are capable of a similar form of SLI.

Then get a 7750 for about the same price and you get far greater gaming performance if you care about it without spending more than $5 to $10 more, if that.

In short no alternative for 6670.
I'm looking for a very small mini ITX gaming box (low profile, single slot graphics)
The 6670 + an AMD A8 APU deliver much better performance.
I would like to see the upcomming A10 and corresponding graphics card.

I hope some company releases a single slot GT 640 or a better Nvidia card so I can finally replace the GTX 460 I got for $110 over a year ago to replace an HD 4650 when it kept having driver issues. That GTX 460 covers up the only other PCIE 1x slot on my HTPC motherboard which I'd like to use.

DON!!!!
There IS a DDR5 version, and a 192-bit version.
The DDR5 version is similar to the 660M.

The 192bit version is not Kepler but a Fermi that was rebadged. Same gpu as the GTS450,GT545,GTX550Ti, :L

well, at least they have 128bit gddr5 Kepler 640 on the list. We can only hope for a comparison review.

Those are OEM only, and won't be available at retail.
Like Ojas mentioned, the 192-bit card isn't new at all, but based on the old GT 545 I believe, which is a crippled version of the GPU from the GTS450

ah didn't know that. Must be, it's PCIe 2.0.
Speaking of re-branding, the 675M appears to be a reworked 580M and the 670M a reworked 570M. Same performance at almost half the clock speed, but they're still the same 40nm Fermi chips.
Slightly off-topic, i find it interesting that the 635M, 630M and 620M are/have versions with 28nm shrinks of Fermi...

I was really excited to see what the 640 would deliver. How disappointing, especially for that price. I'm wanting to build a lan-box for Blizzard/Source/GSG stuff. I guess it's going to be either a 6670 or a 7750. Even bigger bummer since the 7750-2 will need a 6-pin, and I was hoping to keep this little guy on a 250W-300W or below.
Maybe the GT 640 will get a reboot with GDDR5? That would be a good $100 card, and the DDR3 version can sink down to $70-80, much the two 6670s occupy right now.
Great article, I like seeing these lower-budget comparisons for customer builds.
