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
very limited gameplay
average yet very playable
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 we have another bang for buck product, a product that I like very much. As what ATI is doing today is pretty remarkable. They are releasing the Radeon HD 4770, a mainstream product at a budget price. Trust me when I say that after reading this review, you will be impressed.
ATI Radeon HD 4550 512MB review
Today we test the Radeon HD 4550. It's the cheapest desktop graphics product that ATI can deliver at your doorsteps. This Radeon HD 4550 (GPU codename RV710XT) comes with an optional 256 MB GDDR2 or optional 512MB GDDR3 and will cost you .. 45 to 55 USD respectively.
AMD ATI Radeon HD 4870 1024MB review
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.
ATI Radeon HD 4670 review
We test the ATI Radeon HD 4670. A nice little card that packs some decent punch in the value minded consumers.
