GTX 660 Ti & GTX 670 spec Leaked

$249 GTX 660 Ti and $399 GTX 670.

Both has the same memory clock as GTX 680, GTX 660 Ti is the same GTX 680 chips with defects and Nvidia decided to disabled 2 SMXs to reduced CUDA cores, texture units, ROPs and memory interface but still has the same base and boost clocks speed to sell it at very attractive price $249.

I can see the 670 being a good buy at that price, it will more than likely outperform the 7950 which is priced the same. The 660Ti is priced nicely but I'm just not sure exactly how it will perform. I'd say it should be on par with the 7870 for most things that don't use more than 1.5GB of VRAM. This will force prices of the 7870 down - That would be great, but AMD have more room to move on prices for the 78xx series given the smaller die size. Memory prices will be similar, NV use more expensive faster memory but less of it, while AMD use more slower/cheaper memory.

Quantity for NV is the main thing I think. At these prices the demand is going to go through the roof... they must have a lot of semi-defective chips!

Think the 660ti will outperform a GTX 480? I hate this loud, hot, power hungry card.

With 660ti @ 2.35 Tflops and the 480 @ 1.35 Tflops, I'd say it should. I mean come on, 660ti = 1152 cores, 480 = 480 cores. If 660ti doesn't outperform 480, I'll give up on nVidia and draw my screens by hand.

The cores are not the same. Nvidia changed the definition of a CUDA core.

I would think the 660 Ti will outperform the 480, but I can't judge by how much.

[Yaboze]

The memory bandwidth is slightly lower on the 660, but it has the same amount vram, 1536.

Fill rate is higher, as mentioned and power is much better. I was thinking maybe get one of these real cheap without losing performance (I can't afford a 680 or 690 any more) and maybe down the road pick up another for SLI. Maybe.

Those are different types of core, as the GTX480 has double clocked cores, while the 660ti will have single clock ones (all nv cores till Kepler were dual clocked. Kepler changed to single clock, but twice the numbers).

If you want to compare those, 480 core Fermi would be ~ 960 cores for kepler. Check the frequency too though:
GTX 480: 480 fermi cores at 700MHz (1400MHz dual clocked)
GTX 660Ti: 1152 cores at 1006MHz.

Expect around 1.7x perfs.

Don't expect 1.7x performance, you will be disappointed. In most cases the 660Ti should be faster, but by how much I'm not sure. In same cases it could very well be slower due to the lower memory bandwidth, but those shouldn't be too common. Maybe a 670 will suit you better? Guess you'll find out shortly.

[Yaboze]

Yeah, I guess we really won't know until some benchmarks are done.

Accorded to VR-Zone's sources here will be GTX 670 4GB variant.

•$999 - GTX 690 4GB
•$579 - GTX 680 4GB OC (Preferred AIB Pricing)
•$499 - GTX 680 2GB
•$479 - GTX 670 4GB (Preferred AIB Pricing)
•$399 - GTX 670 2GB
•$249 - GTX 660 (Ti?) 1.5GB

If EVGA GTX 680 FTW 4GB still not available in UK in May and June then guess I will wait for cheaper EVGA GTX 670 4GB if it available this month.

$249? I wasn't expecting such a high price. I was expecting something to counter AMD's 7750 in the $120 range. At this rate, we'll see a single slot low profile 7750 before we see a nVidia Kepler equivalent.

Looks like nVidia is still depleting it's stockpiles of GT 430, GT 520, GT 250, etc. before they even consider a low end HTPC type card in 2013.

Seems like a bad time to buy with the new consoles supposedly dropping at the end of the year. Still, this 8800gt is getting old fast, its finally showing its age after all these years. I might bite..just can't quit pull the trigger.
