GeForce GTX 690 review
Posted by Hilbert Hagedoorn on: 05/02/2012 01:00 PM [ 0 comment(s) ]
A couple of days ago NVIDIA announced a new graphics card, correct, the GeForce GTX 690 has surfaced. A bit unusual as at first the product was announced, and then later on released in stores and submitted to the press. The all new dual-GPU beast called GeForce GTX 690 however has landed at the premises of Guru3D.com and it is time to give it the royal Guru3D treatment.
So albeit the product really doesn't need any introduction, in a nutshell, NVIDIA took two of their best (Kepler GK104) GPUs, placed them onto one card, topped it off with a very nice and dandy cooler and called this symbiosis of components a single solution graphics card. Internally on that card a small PLX chip functions as a PCI Express bridge in-between the two GPUs and sure, that means SLI is in full effect. The release today is very interesting as the GTX 690 is amongst the most silent multi-GPU solutions we have ever had our hands on, the performance really is quite seriously staggering and despite all that brute force the power consumption remains very acceptable.
The end result is a beast of a graphics card that renders games atrociously fast, even with the most stringent image quality settings. Obviously the GeForce GTX 690 will break massive records in 3D performance as the performance is nearly equal to a pair of GeForce GTX 680s in SLI. The two PLX bridged Kepler GK104 GPUs provide 3072 Shader cores. They are paired with two 2GB memory clusters at 6 GBPs (4GB in total).
The GPUs on the GeForce GTX 690 have a boost clock of 1019 MHz, and that's less than 3% away from the GeForce GTX 680 at 1058 MHz, so that sounds pretty terrific. All other specs are identical; the number of shader processor cores, memory speed, and memory bandwidth per GPU are the same on both cards.
The first impressions of the board are really good, a nice sturdy design, the cooler is nearly a work of art -- we'll talk about it guided with some photos though as there is much to talk about. Looking at the printed circuit board (PCB) we spot a vigorous 10-phase digital PWM design for the cores themselves while the memory will likely receive its own 2-phase grid allocated. Two 8-pin PCI-E connectors feed the card. NVIDIA is giving the GTX 690 a maximum power target of +35%, which given the cards default power target of roughly 265W means it can be set to draw up to ~350W, and that means you'll be able to overclock nicely as well.
Display connectivity then; NVIDIA uses the same 3x DL-DVI and 1x miniDP port configuration that is used on the GTX 590. That will allow for three connected monitors over DL-DVI. Now these are just the first impressions, we are going in-depth over the next few pages of course. We do need to mention that that card is very expensive at a price of 999 USD / 949 EUR. Have a peek at the awesomeness that is the GeForce GTX 690, and then head on over to the next page where, as always, we'll go a little deeper, but not too deep. We'll look at noise levels, power consumption, heat, we'll do a nice photo-shoot and an extensive benchmark session to see where this product positions itself. Next page please.
In this article we review the ASUS GeForce GTX 670 DirectCU Mini edition, a compact performance graphics card designed primarily for small form factor PCs with mini ITX motherboards. The dual-slot card measures just 17cm and features the NVIDIA GTX 670 GPU. ASUS has re-engineered the DirectCU cooler to fit small form factor cases. While shorter, it introduces a copper vapor chamber placed directly on top of the GPU for faster heat spreading and dispersal with 20% lower temperatures than reference GTX 670.
MSI GeForce GTX 650 Ti BOOST OC review
In this article we review the MSI GeForce GTX 650 Ti BOOST OC edition review with that OC for a factory tweak. The product is customized with a new PCB, cooling and a few tweaks, it has 2GB of memory with both that memory and the core base-clock slightly overclocked. Overall an interesting product at an interesting price in the lower segment of the mainstream market.
EVGA GeForce GTX 650 Ti Boost SC edition review
In this article we review the EVGA GeForce GTX 650 Ti Boost SC edition review with that SC for superclocked. The product is fairly reference looking but does come with EVGA's own styled cooler, it has 2GB of memory with both that memory and the core baseclock slightly overclocked quite significant.
Palit GeForce GTX 650 Ti Boost OC edition review
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.
