Not many people would argue that the AMD 5xxx series has been an incredible success … fantastic performance, wicked DX11 capabilities while still managing to remain competitively priced. In the latest of our articles to focus on graphics cards with proprietary cooling systems we look at a product called the Formula HD5750. Yep, if you look closer you will see that the cooler is shaped to resemble a Formula race car.
Its that time of year again where NVIDIA have a new series of cards in the pipelines and as we have seen running up to today, the number of rumours and leaks that have been flying about are as profound as ever. For some this leads to pure confusion as to what is to be seen and what is complete rubbish, and for people like myself it leads to pure frustration as I know all the true facts and figures, meaning that when I see the rumours and false facts floating around I can do nothing but sit and wait until the NDA lifts to put a number of these claims to rest with the real specifications and performance figures behind the new cards.
So here we have it, the GTX 780 - the first in the new line of Kepler based 700 series cards and before we get too far into the nitty gritty of what's new in the 700 series, I want to make the following fact clear and true - the GTX 780 CANNOT be flashed in any way to effectively turn it into Titan. There are a number of reasons for this; first off, whilst both cards share the same GK110 core, the 780 has far less CUDA cores, is a different revision of the core chip and has less texture units on-board. On top of this, there is also half the amount of video memory and a number of components in the power region of the PCB are missing as the 780 does not require these as opposed to Titan.
Point out of the way, NVIDIA's new 700 series cards are here to replace the ever popular 600 series, although they are not a re-hash and re-brand of 6xx cards as some may presume. Whilst the GK110 cores may be featured on both 600 and 700 series cards, they will have subtle variances to them, mainly on the front of CUDA core count and texture filters and so forth.
So what is the 780 in relation to the 600 series cards. Whilst it may look like Titan, it is a slightly lower performing card. Titan is more geared towards users with multiple high resolution displays and thus the higher 6GB of GDDR5 memory that it encompasses. The 780 whilst still home to 3GB of GDDR5 is more aimed at users who are going to be gaming on a single screen at high resolutions with all the settings turned to 11. Over its predecessor, the GTX 680, the 780 has 50% more CUDA cores with a count of 2034, 50% more memory, up to 3GB from 2GB and overall a 34% increase in performance. Interestingly enough, GTX 580 users who upgrade to a 780 will see a whopping 70% gain in performance between the two cards and a 25-30% gain can also be found over AMD's 7970.
The Black Edition series from XFX has served us extremely well since the launch of the new HD 7000 series this year. We saw XFX come out strong with the HD 7970 version which was then followed up with the HD 7950 version.
After that we saw the HD 7770 get the same treatment, but unfortunately the HD 7770 on a whole hasn't been our favorite model due to the current price point it hits at. Today it's time to check out the HD 7870 version of the Black Edition card and see how it goes.
GeForce-GTX-670/680-Roundup Die Asus GeForce GTX 670 und GTX 670 DirectCU II OC , EVGA GTX 680 FTW, KFA GTX 680 EX OC, MSI GTX 670 PE OC und die Zotac GTX 670 und GTX 680 AMP! im großen Vergleichstest.
Firing up 3DMark 11 we ended up with a score of P3580 which is exactly what we'd expect from the HD 7770. It's not a bad score, but our issue has always been compared to the HD 6870 which sits at a similar price point at the moment, the HD 7770 comes off looking quite overpriced.
What was really nice though was the cooler which let the GPU sit at 35c when idle and still quite a cool 51c at load. More surprising, though, was the cooler which came in at 54.4dB at idle and 55.1dB at load. These are good numbers which see this as the second coolest running card and quietest active cooled card we've tested recently.
Today we grab a third card and see what happens when we move to a three way CrossFireX setup. Since we've already looked at the Sapphire card in full detail in our CrossFire review mentioned above, we'll be getting into the performance side of things fairly quickly today.
The first thing we need to do is just take a quick look at our testbed, if you've been following our HD 7970 series of content, though, you shouldn't see anything out of the ordinary. Once we've done that we'll move onto the performance of the setup and see how it compares to other HD 7970s we've looked at.
We take a look at another new TOXIC series video card from Sapphire. This time it's the lower-end Radeon R9 270X 3GB model.
So far we've had some good success when it comes to overclocking which we looked at in our HIS HD 7970 and XFX HD 7970 Black Edition Double Dissipation review. Adding a second card into the mix is known for limiting overclocking ability as cards are placed together and more heat is generated. Those numbers are then amplified due to the added voltage being thrown through the core of each GPU.
Since we've already looked at the Sapphire HD 7970 in our original CrossFire review, we won't need to have a look at the card again. Instead we'll get straight into the testbed setup and quickly cover how we went with the overclock. Once we've done that we'll just get straight into the performance.
Today we shall review a trio from HIS based on the Radeon HD 6970, Radeon HD 6950 and Radeon HD 6850 GPUs. Some of these solutions copy reference design, but every card is nevertheless factory-overclocked and has a rather efficient cooler.
