ATI Radeon HD 4770 review -
VGA performance: 3DMark Vantage (DX10)
3DMark Vantage (DirectX 10)
3DMark Vantage focuses on the two areas most critical to gaming performance: the CPU and the GPU. With the emergence of multi-package and multi-core configurations on both the CPU and GPU side, the performance scale of these areas has widened, and the visual and game-play effects made possible by these configurations are accordingly wide-ranging. This makes covering the entire spectrum of 3D gaming a difficult task. 3DMark Vantage solves this problem in three ways:
1. Isolate GPU and CPU performance benchmarking into separate tests,
2. Cover several visual and game-play effects and techniques in four different tests, and
3. Introduce visual quality presets to scale the graphics test load up through the highest-end hardware.
To this end, 3DMark Vantage has two GPU tests, each with a different emphasis on various visual techniques, and two CPU tests, which cover the two most common CPU-side tasks: Physics Simulation and AI. It also has four visual quality presets (Entry, Performance, High, and Extreme) available in the Advanced and Professional versions, which increase the graphics load successively for even more visual quality. Each preset will produce a separate, official 3DMark Score, tagged with the preset in question.
The graphics load increases significantly from the lowest to the highest preset. The Performance preset is targeted for mid-range hardware with 256 MB of graphics memory. The Entry preset is targeted for integrated and low-end hardware with 128 MB of graphics memory. The higher presets require 512 MB of graphics memory, and are targeted for high-end and multi-GPU systems.

With 3DMark Vantage we look at the three main results it returns in the "P" performance test. Fairly impressive numbers really. A lot can be said about the 3DMark series, yet the GPU test really is good and reproduces a very reliable number that scales pretty darn well and trustworthy.
With the 4770 you can expect a GPU score of roughly 6600 points, and 8000 points in the P score depending on your system specifications.
Mind you that for GeForce CUDA ready graphics cards PhysX is always disabled in our tests (enabling would affect CPU and overall P score).
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.
