I think it is fair to say that it is 20 to 25 percent faster compared to the DDR3 version. Check my results (only one computer, all GT240 results) if you want to compare them.



I looked.

It is as you say.

I think that's the fastest GT240 I've ever seen. You obviously have adjusted well.

"To buy, or not-to-buy; that is the question."

Okay, so by overclocking, fiddling-with, and otherwise practicing voodoo, you can get a GT240 or a GT640 to perform much better than the manufacturer intended. It's much more likely to be successfully done with faster RAM and extreme cooling.

Of course you can.

That was never the question.

You can do the same thing with a 550Ti, or a 560, or a 580, or a 690, or a 520 (good luck with that). We can always push the cards. The wizards can always push the programs.

My interest isn't the same as you might find on an overclocking forum or in a contest; although I am able to appreciate what others do.

I really don't have a month to spend tweaking video cards. (that's why my overclocked cards are factory overclocks and I don't push them beyond that, and the only CPU/motherboard overclocks I've used are the "push a button" types which get one chance to be stable) The only fiddling I do is when I'm asked.

I know that makes me boring.

I'm just assessing if the GT640 is "a worthy cruncher" at its price-point compared with the alternatives, and thus-far I'm thinking "probably not."

Could that dynamic change with a DDR5 version overclocked to heck and back?

I doubt it.

You can get so much better performance from a standard, boring, 550Ti right out of the box for just a very little more money. Even if the GT640 could be "forced" to perform all the way up-to the standards of a 550Ti with endless tweaking and ragged-edge adjusting, why bother?

You could always get the 550Ti and do the same thing.

I am rapidly concluding that the GT640 is the first, good, GT240 substitute if that's exactly what you need. Otherwise, pass-it-by.

Of course, that's just one man's opinion and I'm really not personally invested in it, so it's fine with me if others draw a different conclusion. You'll get no argument from me.

We’re expecting NVIDIA will launch a GDDR5 variant at some point, but, for the first round of cards, GT 640 is exclusively DDR3. This has important performance repercussions... NVIDIA is launching with DDR3 here, which means that even with the 128-bit memory bus this card is extremely memory bandwidth starved. At just shy of 1.8GHz it only has 28.5GB/sec of memory bandwidth. DDR3 versus GDDR5 has been a recurring issue in this market segment, and as both GPU performance and GDDR5 performance have increased over time the gap between DDR3 and GDDR5 card variants has continued to grow. By the time we’re up to this many ROPs and shaders the memory bandwidth requirements are simply enormous. In traditional fashion these DDR3 cards are outfitted with more memory overall – the DDR3 GT 640 ships with 2GB – so it has a memory pool every bit as large as the GTX 680’s but lacks the memory bandwidth to make effective use of it. So expect the obligatory 1GB GDDR5 version to be much faster here.

AnandTech - GeForce GT 640 DDR3 Review: Glacial Gaming & Heavenly HTPC

...the massive increase in ROPs coming from GT 440 to GT 640 doesn’t help the GT 640, which means the GT 640 is relying on the smaller increase in shader performance. The end result is that the GT 640 neither greatly improves on the GT 440 nor is it competitive with the 7750. Compared to the GT 440 compute shader performance only improved by 28%...

Anandtech GeForce GT 640 DDR3 Review - Compute and Synthetics

...Our final benchmark is a look at CUDA performance, based on a special benchmarkable version of the CUDA Folding@Home client that NVIDIA and the Folding@Home group have sent over. Folding@Home and similar initiatives are still one of the most popular consumer compute workloads, so it’s something NVIDIA wants their GPUs to do well at.



Folding@Home has historically pushed both shader performance and memory bandwidth, so it’s not particularly surprising that the GT 640 splits the difference. It’s faster than the GT 440 by 32%, but the GTS 450 still has a 25% lead in spite of the fact that the GT 640 has the greater theoretical compute performance. This is another test that will be interesting to revisit once GDDR5 cards hit the market.

I'm really glad you posted this.

I was wondering about the GTS 450. I can't buy 'em all to try, but I think we've got our answer about the GT640 in this excellent explanation.

And I just saw a GTS 450 on newegg.com for $70 after rebate.

Have a great Summer, setizens!:D

I'm gonna be pretty much offline 'till September so feel free to hijack this thread! Especially if a 660 (and 650) or 7990 comes out.

Wish ya all the best!

I just GOTTA open with this one:



Good news for Seti crunchers?:)



AnandTech
"Compared to the GTX 670 it’s a bit slower, a lot cheaper, and still brutally efficient. For buyers who have wanted to pick up a Kepler card but have found the high-end GTX 670 and GTX 680 out of their price range, at $300 the GTX 660 Ti is at a much more approachable point on the price-performance curve, offering about 88% of the GTX 670’s performance for 75% of the price. Given the price of Kepler cards so far this is definitely a better deal, though it’s still by no means cheap"

"If you're lookign for a new graphics card, the GTX 660 Ti will provide all the benefits of the Kepler architecture. We've seen in our tests that the GTX 660 Ti outran the last year's top card the GTX 580, which really says enough."

Now if they would just come out with something to fill the gap between the GTX 650 and the GTX 660, hopefully a GTX 650 Ti maybe?

Cheers.

No, they are both PCIe cards.
