So if we look back, say roughly a year .. what were the two products that had the most impact and success? Yeah, I tend to think that was the release of Core i7 and the Radeon 4870 based on the RV770 graphics processor. Last year when ATI introduced their Radeon HD 4870 series product it was clear from day one and onwards that they designed an ASIC which was very powerful, and thanks to gDDR5 memory, a big performance leap at an affordable price was a reality.
Prolonging the success of the 4870... in early April this year ATI launched a respin ASIC called the Radeon HD 4890. As you guys likely know this is labeled as the RV790 ASIC, a slightly tweaked yet faster running version of that original model.
One of the biggest surprises of that RV790 graphics processor was its scalability in terms of clock frequency. Where the Radeon HD 4870 reference was clocked at 750 MHz, the Radeon HD 4890 was from day one clocked at 850 MHz. But it didn't stop there though, no Sir. Merely a week or two after the launch of the 4890 the first rumors, and later on press-releases, surfaced; the AIB, AIC partners of ATI would be releasing overclocked models of the Radeon HD 4890, which was just barely released. 900 MHz is the norm for most of the overclocked products. The really exquisite ones are clocked at 950 MHz and right now there are even cards being released with a 1000 MHz core clock frequency (!).
As such it is the first time ever that we are testing a graphics card with it's graphics core clocked at 1 GHz, and this editor actually finds that to be a milestone in the history of Guru3D.com
So when we look all the way back to that Radeon HD 4870 and compare it to the new faster clocked 4890 models, we surely have to admit, ATI and its partners have done a hell of a job moving forward at a steady and incremental pace. Today we will test and review the all new MSI Radeon HD 4890 Cyclone SOC edition (Super OverClocked), and oh-my-gosh ... for the money this thing is going to be fairly spectacular.
Have a peek at the product and then let's move onward to a nice in-depth review of the MSI Radeon HD 4890 Cyclone SOC
Overclocking the Radeon HD 4890
This week the Radeon HD 4890 was released by ATI and as our reference article showed, it has a lot of overclocking potential. I mean seriously, it has a lot of headroom there which could results in 10% better performance on average.
Typically overclocking can be managed really well through the Catalyst control center, however .. the control center always has certain restriction as in 'how much' you can actually overclock. In this article we'll show you how you can overclock the easy way, with the help of this little application we make ourselves, Rivatuner.
This article is really simple as all we'll show you is, how to manage an overclock; and of course throw in a couple of additional benchmarks.
Overclocking & Tweaking
As most of you with most videocards know, you can apply a simple series of tricks to boost the overall performance a little. You can do this at two levels, namely tweaking by enabling registry or BIOS hacks, or very simple, tamper with Image Quality. And then there is overclocking, which will give you the best possible results by far.
What do we need?
One of the best tool for overclocking NVIDIA and ATI videocards is our own Rivatuner that you can download from our website. If you own an ATI or NVIDIA graphics card then the manufacturer actually has very nice built in options for you that can be found in the display driver properties.
Where should we go?
Overclocking: By increasing the frequency of the videocard's memory and GPU, we can make the videocard increase its calculation clock cycles per second. It sounds hard, but it really can be done in less than a few minutes. I always tend to recommend to novice users and beginners not to increase the frequency any higher then 5% (in total) of the core and memory clock MHz.
