Palit is back at it with some JetStream cooling
In this review we'll look at the GeForce GTX 660 Ti from Palit, it's their all beefed up version, the GeForce GTX 660 Ti JetStream version.
One of the most anticipated dedicated graphics card series for a long time now is the GeForce GTX 660 Ti series. There has been so much speculation and gossip about it. Today NVIDIA finally lifts the curtain on that product, and let me already say it loud ... it's a gem !
Pretty much everybody anticipated a new 'mid-rang' GPU, but we've stated it for a long time now, the GK104 Kepler GPU originally was intended to be the mid-range product series. However it came out too good, so NVIDIA decide to use the that GK104 Kepler GPU for the GeForce GTX 680, then the GeForce GTX 670 and now .. it's being used on the GeForce GTX 660 Ti as well. Oh and yes, the Ti extension has been reintroduced once again.
Being based on the GK104 Kepler GPU obviously NVIDIA had to put some breaks on it in order for the 660 series of product not to compete too much with their bigger brothers. As such they trimmed down the number of shader processors a little towards 1344 of them. Now keep in mind that the mighty GeForce GTX 680 has 1536 of them so that's what, 15% less shader processors. More interesting is the fact that it's precisely the same amount of shader processors as the GeForce GTX 670 has, so you can already 'feel' where the performance levels are heading. There are two distinct difference though, the GeForce GTX 670 and 680 uses a 256-bit memory bus, and the GTX 660 Ti series will get a 192-bit memory bus tied towards 2 GB of memory. But with the memory running at 6008 MHz in combo with the memory bandwidth gDDR5 memory these days offers, really the difference will be noticeable but not that big. The second one is the ROP engine, now cut down to 24 units opposed to 32 on it's bigger brothers.
Not one AIC partner from NVIDIA will follow up with this at launch, but the reference product will be clocked at 915 MHz, it's allowed to boost towards 980 MHz (again similar to the GTX 670) and the TDP of the GeForce GTX 660 Ti is going to be set at 150 Watt, while in your average gaming experience the card really uses like 135 Watt.
So it isn't hard to understand that the factory overclocked GeForce 660 Ti SKUs will run as fast as and maybe even faster then a GeForce GTX 670 (reference clocked) and maybe .. just maybe even close in on a reference clocked GTX 680. The GeForce GTX 660 Ti series will be launched in the 300 USD range, 259 EUR ex VAT in Europe. And for that money it's going to shock and awe alright. Before we startup the review let me blast a quick myth our of the virtual skies, the rumor of a 256-bit version of this card has been denied by NVIDIA. And truthfully, if such a card existed .. it would be 1:1 a GeForce GTX 670.
As stated there will be lots of SKU's released by the many board partners, in this review we'll look at Palit's offering in the form of a Jetsream offering, it's factory overclocked, customized and custom cooled much like all board partners have. Let's head on over to the next page shall we ?
For this review we test and benchmark the Palit GeForce GTX 650 Ti Boost OC edition. The product comes customized with their own PCB design, a dual-fan cooler, 2GB of memory with both that memory and the core baseclock slightly overclocked.
Palit GeForce GTX 660 Ti Jetstream review
In this review we'll look at the GeForce GTX 660 Ti from Palit, it's their all beefed up version, the GeForce GTX 660 Ti JetStream version. The GTX 660 Ti again has been equipped with a JetStream series cooler yet which remains a 3-slot design. It runs at a core clock frequency of 1006 MHz, has a boost frequency of 1085 MHz and the effective memory data rate (192-bit) is 6108 MHz.
Palit GeForce GTX 670 JetStream review
We review the Palit GeForce GTX 670 JetStream graphics card. the JetStream version which comes pre-overclocked at 1006 MHz on the baseclock and an impressible 1084 MHz on the boost clock. More interestingly, the boost clock during our test sessions was actually closer to 1200 MHz most of the time (!). To give the card enough framebuffer to work with the cards are equipped with 2048 GDDR5 on a 256-bits wide bus. Palit clocks this memory at 6108 MHz.
Palit GeForce GTX 680 4GB Jetstream review
We review the Palit GeForce GTX 680 4GB Jetstream edition. Why 4 GB ? Well some of you like to game at extremely high resolutions or have 8xAA as a bare minimum. If a graphics card runs out of graphics memory it'll starts swapping frames back and forward in that framebuffer which decreases the overall framerate. So today we'll look at the 4GB model, we'll specifically place a focus at some tests at 2560x1600 with a good chunk of AA enabled to see what difference the extra 2GB graphics memory will bring us in terms of performance.
