| Gainward GeForce GTX 650 Ti 2GB Boost Golden Sample Video Card in SLI Overclocked Review @ TweakTown |
We take a look at our second retail GeForce GTX 650 Ti Boost in the form of an offering from Gainward and see how it performs when in SLI mode and overclocked.
We are looking at a high-end Radeon HD card from ASUS. It's their ASUS Radeon HD7790 1GB DirectCU II OC. A default Overclocked Graphics Card. We have tested several factory overclocked cards in the same segment, so let's see how the ASUS Radeon HD7790 1GB DirectCU II OC performs.
The latest AMD Radeon HD 7790 GPUs feature a revised AMD PowerTune Technology implementation, with 8 states, more shader units compared to the versions and higher frequencies. The XFX Black Edition implementation comes with raised speeds from the factory and an enhanced Double Dissipation cooling system for a good efficiency, while maintaining low noise levels.
By the grace of TUL Corporation, we have been presented with a PowerColor PCS+ HD 7870 MYST Edition. PowerColor themselves are a Taiwanese subset of the previously mentioned TUL corporation, and are licensed producers of the ATI Radeon cards, as well as Nvidia cards, which they release under the Zogis brand name. Since PowerColor has the ability to change the specifications on the cards they sell, most of their cards are overclocked by default, something of a double-edged sword in my opinion, but more on that later. Ranging in price from $235 and $263 depending on the retailer, this card, with its great many features is possibly within the higher ends of availability for most consumers.
Am heutigen Donnerstag startet NVIDIA seine neue Grafikkarten-Serie mit der Vorstellung der GeForce GTX 780. Die GTX-700-Serie soll dabei nach und nach die bisherigen Modelle der GTX-600-Serie ablösen. Was es für Neuerungen gibt und wie sich die GTX 780 in der Praxis schlägt, dass verrät unser Testbericht.
Based on the GK104 GPU used on cards such as GTX 680 we have three factory overclocked versions of the GTX 770 on our test bench and all have their own custom design. We'll be putting them through a selection of real world tests against overclocked 680 and 7970 cards (as well as GTX 780) to see how they do in titles like Crysis 3, Metro: Last Light and Grid 2.
Last week we saw the release of NVIDIA's latest graphics range - namely the 700 series and its top model, the GTX 780. In many respects the GTX 780 brings a whole new level of performance to a greater audience and as I showed, there is only a small difference between the 780 and Titan on a single screen.
Working through the new 700 series line-up, NVIDIA are now lifting the lid on their next card, the GTX 770. Like the GTX 780, the GTX 770 has had many rumours surrounding its release and like the 780, these are all related to specifications, performance and most of all the GK104 core and a GTX 680. Like the GTX 780 I first of all want to put one of these rumours to rest and state the reason why. The one that I am referring to is the speculation that GTX680 owners would be able to turn their card into a GTX 770 through a BIOS update. Simply put this CANNOT be done. Whilst both cards share the same GK104 GPU core, there are a number of factors that lead to this impossibility. Like the 780 to Titan comparison, the GTX 770 has a slightly different revision of the GK104 core with varying number s of CUDA cores and texture units, however the most significant factor for the inability to 'convert' the GTX680 lies with the on-board memory.
One of NVIDIA's major shouting points with the GTX770 is the inclusion of memory that runs at a whopping 7Gbps at stock, these are no overclocked ICs either, they are entirely new, so unless you have the ability to unsolder and resolder the ICs on to a GTX 680 as well as change the PCB layout slightly, there is no possibility of changing your card from one to the other.
The ZOTAC GeForce GTX 650 Ti Boost features two key improvements over the reference model; the first is this card utilizes their advanced Dual Silencer thermal solution and it also features improved performance out of the box via higher clock frequencies.
Another week goes by, and Nvidia launch another graphics card, as we've seen recently with the GTX 780 and 770. Today however sees the more wallet friendly GTX 760 which is said on the grapevine to be the last Nvidia GPU launch for 2013, but as we know with rumours, it's just a matter of seeing what the future holds.
When Nvidia launch a card, they sometimes provide reference samples, but for the most part, they rely on their partners to manufacture their own creations and sometimes that may mean us getting a sample with a unique cooling solution or pre-overclocked speeds, or in today's case from KFA2; we get the benefit of both.
It's been a while since we've worked with KFA2, but after discussing through the launch with them, we find the GTX 760 EX OC landing in our offices, offering us a pre-overclocked GPU and a custom cooler design that we originally saw on the GTX 660 when that launched. Based on the overclock speeds that KFA2 have managed to secure on this card, we hold high hopes that we should see performance very close to that of the GTX 770, but of course there is only way to find that out, and that means throwing the card on our test bench and seeing what it can do.
Of course, we have a few other things to take care of first, consisting of taking a look at the packaging on offer, before delving into the design and aesthetics of the card. Once this is out of the way, we will look at how KFA2 have pushed this card beyond stock figures, before jumping into the performance straight out of the box.
Also, wanting to squeeze the very best performance from the card, we will be overclocking it even further than what KFA2 have, and if previous 700 series GK104 counterparts are anything to go by, we should see some really high numbers here today, so lets get straight into it and see what magic treatment KFA2 have given the GTX 760 graphics card.
We take a look at our first GTX 760 2GB product from MSI with its new GeForce GTX 760 2GB Twin Frozr Gaming OC video card. We also overclock it further to see what it can do.
