A word about "FPS"
What are we looking for in gaming performance wise? First off, obviously Guru3D tends to think that all games should be played at the best image quality (IQ) possible. There's a dilemma though, IQ often interferes with the performance of a graphics card. We measure this in FPS, the number of frames a graphics card can render per second, the higher it is the more fluently your game will display itself.
A game's frames per second (FPS) is a measured average of a series of tests. That test often is a time demo, a recorded part of the game which is a 1:1 representation of the actual game and its gameplay experience. After forcing the same image quality settings; this time-demo is then used for all graphics cards so that the actual measuring is as objective as can be.
|Frames per second||Gameplay|
|<30 FPS||very limited gameplay|
|30-40 FPS||average yet very playable|
|40-60 FPS||good gameplay|
|>60 FPS||best possible gameplay|
- So if a graphics card barely manages less than 30 FPS, then the game is not very playable, we want to avoid that at all cost.
- With 30 FPS up-to roughly 40 FPS you'll be very able to play the game with perhaps a tiny stutter at certain graphically intensive parts. Overall a very enjoyable experience. Match the best possible resolution to this result and you'll have the best possible rendering quality versus resolution, hey you want both of them to be as high as possible.
- When a graphics card is doing 60 FPS on average or higher then you can rest assured that the game will likely play extremely smoothly at every point in the game, turn on every possible in-game IQ setting.
- Over 100 FPS? You have either a MONSTER graphics card or a very old game.
Today a test and review on the new AMD ATI Radeon HD 4870 1024MB. Obviously ATI is releasing a 1GB model to compete with the new Core 216 version of that GeForce GTX 260. The 4870 series really diggs that GDDR5 memory bandwidth, and what's the cheapest thing to do to gain some extra performance ? Increase the framebuffer volume. Now that by itself is not going to work miracles, yet in memory limited situations (loads of high quality textures, filtering and AA modes) it will help you here and there. And a little bit of extra bite is all the product needs to get beat that Core 216 card again.
AMD ATI Radeon HD 4850 Crossfire
A review with Crossfire results as well, on the all new Radeon HD 4850 from Force3D and PowerColor. Definitely a review worth reading.
AMD ATI Radeon 3850 & 3870 review
Today AMD will launch the Radeon 3000 series products, in specifically the Radeon HD 3850 and 3870. I'll give you a quick hint, these cards are roughly as fast a Radeon HD 2900 XT .. yet they are priced a very promising level; how does a price range of 149 to 249 USD sound ? See, performance wise a 149 USD Radeon HD 3850 will wipe the floor with the entire competitors GeForce 8500/8600 series easily and the 3870 will put up a great fight with the 8800 GTS. With new releases often also we can see a couple of new tricks. Today's announced products will see light of in the form of DirectX 10.1 support, the new UVD (video de/encoding) engine is now integrated opposed to the 2900 XT which didn't have it. Full PCI-Express 2.0 support, and a die-size based on 55nm to die for.
