Radeon HD 5870 Review

Okay, the next new hot feature for ATI Radeon graphics cards was already announced, ATI's Eyefinity. ATI introduces Eyefinity technology on their Radeon HD 5000 series graphics cards. This literally boils down to multi-monitor desktop and gaming nirvana! You will have no problem connecting say, three 30" monitors at 2560x1600. The graphics card can take that resolution and in fact combine the screen resolution and play in it.
We can explain this really simply though; you guys remember our Matrox Triplehead2Go reviews right? Well, ATI's Series 5000 graphics cards will be able to drive one to six monitors per graphics card. We've seen and tested this live in action, and it works really nicely. You can combine monitors and get your groove on up-to 7680x3200 pixels separated over several monitors -- multiple monitors to be used as a single display. I think the limit is even 8000x8000 pixels, but don't hold me to that.
So some examples of what you can do here:
- Single monitor setup at 2560x1600
- Dual monitor setup at 2560x1600 per monitor
- Three monitors setup at 2560x1600 per monitor
- Six monitors setup at 1920x1080 per monitor
Eyefinity is looking really nice, and sure we also understand that 99% of you guys will never use more than two monitors. That other 1% definitely matches the Guru3d audience. Personally I like to game on three screens. It's really immersive.
Mind you that for six monitor support a special edition (Eyefinity6) card will be launched with six display ports. Your average Radeon HD 5870 will have three or four monitor outputs. In fact the reference 5870 has two DVI, one HDMI and one display port connector all on one card. If you are bold enough to go for a multi-monitor setup, it really is ideal to get three screens for flight sims, racing games, role paying games, real-time strategy, first-person shooters and sure, even multimedia apps.
At ATI's press events they hooked up the Radeon HD 5870 to half a dozen DisplayPort outputs that were running at their full resolution, merging all six into a solitary image to hit a phenomenal live display. Eyefinity is modular and thus allows users to rearrange the number of discrete images created in addition to their shape according to your liking. Guru3D users and gamers will no doubt find this setup to their liking. It will be interesting to learn just what kind of living room you have if you were to employ such a configuration. Please post your setups in our forums.
Also a note -- we'll be publishing a dedicated article on Eyefinity in the future, but we expect this to be a great feature for all kinds of simulations, the flight-sim community must be going wild for sure allright !
One of the biggest accomplishments of the series 5000 graphics cards is the enhancement in the power design, the implementation of voltage and clock regulation is even more dynamic -- power management at a new level.
So we'll look purely at the Radeon HD 5870 now, in IDLE the GPU will clock down and lower its voltages on both GPU and memory. Have a look:
|GPU||Radeon HD 4870||Radeon HD 5850||Radeon HD 5870|
|Max. Board Power (TDP)||160W||170W||188W|
|Idle Board Power||90W||27W||27W|
The card obviously achieves a low 27W IDLE power consumption by clocking down with several power states. Thus a low engine (core) clock frequency with lowered voltages and lower GDDR5 memory power. It's amazing though as your generic high-end graphics card would normally consume 50~60 Watts when it idles in Windows.
Things get even better though, the performance of the graphics card opposed to the last generation products has nearly doubled up in performance and design, yet the 5870 has a TDP (peak wattage) of only 188 Watts. We think that is just awesome.
Though we haven't tested it yet, ATI also incorporated a new technology feature called ULPS -- Ultra High Power State for multi-GPU configurations. We need to look into this, but typically with multiple GPUs installed you'd have a high IDLE power consumption, this seems to have been improved. More on that in another article though.
We will test power consumption later on in this article.
We test and review the MSI Radeon HD 7790 OC edition, also known under SKU code R7790-1GD5-OC incl FCAT Frametimes. The new graphics card is intended to boost a little more performance into entry-level gaming.
Gigabyte Radeon HD 7790 2GB OC review
We test and review the Gigabyte Radeon HD 7790 2GB OC edition, also known under SKU code GV-R7790OC-2GD. We benchmark the product incl FCAT Frametimes. The new graphics card is intended to boost a little more performance into entry-level gaming. The Gigabyte HD7790 OC 2GB clocks in at 1075 MHz on the boost engine, packed with totally silent custom cooling.
Radeon HD 7990 review
We review the new AMD Radeon HD 7990 including FCAT frametime measurements. The dual GPU product that you guys learned to know under codename Malta finally is released. AMD it doing it in style, two fully equipped Tahiti XT2 GPUs versus good yet silent cooling. In this review we'll look at the product, the architecture, the benchmarks, including frametime based FCAT measurements. Head on over towards our AMD Radeon HD 7990.
Club3D Radeon HD 7870 Joker review
We test and review the Club3D Radeon HD 7870 Joker, this is the much discussed 7870 card that in fact has a 7900 series GPU, the Tahiti LE. For a fair amount of money this series 7800 product now offers 7900 series performance. Armed with 2GB of graphics memory it hits a sweet spot gaming performance wise and to date it one of the more popular products in the mainstream segment. Let's check out the Club3D Radeon HD 7870 Joker.
