Don't Miss: Best Gadgets of 2017
The XFX ATI Radeon HD 4770 is a PCI Express 2.0 x 16 video card that has a clock speed of 750Mhz and features 512MB of GDDR5 RAM. The card supports a maximum resolution of 2560 x 1600 and has HDTV out. The card is HDCP compatible for Blu-ray. Other features include 640 stream processors, OpenGL 3.0 support, DirectX 10.1 support, and support for ATI Avivo HD video and display technology.
The test machine I will be using in this review has the following specifications:
To test the XFX ATI Radeon HD 4770 I will be using 3DMark Vantage, Crysis, and Call of Duty: World at War. The first test up is 3DMArk Vantage.
I ran 3DMArk Vantage at default settings in the application and in the ATI control panel. The XFX ATI Radeon HD 4770 scored a total of P7383 on the benchmark. The GPU score was 6594 and the CPU score was 11513. To compare, the GPU score for the XFX HD 4890 XXX was 10241, that card is several steps above the XFX ATI Radeon HD 4770 I am testing today in price and performance though.
The next test is with Crysis. This game has been around for a while, but it is still very popular and one of the most demanding titles around. I ran the game at 1920 x 1200 resolution with 2x AA and all settings on medium. I used Fraps to record frame rates while playing the game from the initial beach insertion until the fight with the first two enemy soldiers. Fraps recorded the following frame rates:
To compare the 4890 XXX had an average frame rate of 59.431 at the same settings, save an increase of 4x AA compared to 2X AA I used here. Crysis played smoothly and without noticeable stuttering or any other issues on the XFX ATI Radeon HD 4770 at these settings.
Call of Duty
The final game test is Call of Duty: World at War. This is one of my favorite games and it has great multiple player action. I again used fraps to record frame rate data while playing the game after the player is rescued from the Japanese. I used settings of 1920 x 1200, 4X AA, all settings on except sync frame rate and dual video cards. Fraps recorded the following frame rate data:
The average frame rate with the same settings for the 4890 XXX was 68.738 fps. The XFX ATI Radeon HD 4770 did very well at these settings with COD and the game was fluid and very playable at these settings.
I came away happy with the way the XFX ATI Radeon HD 4770 performed. This video card played two of the most demanding games on the market at settings that look fantastic on a large 24-inch LCD without any issues. The best thing about the XFX ATI Radeon HD 4770 is that the video card can be purchased online for under $120 making it a steal for a budget gamer.
The worst thing I can say about the XFX HD 4770 is that it lacked a game bundle. At the low price, that the video card sells for that caveat is very easy to overlook. You can get a pair of these cards for some Crossfire action for under $250. The performance for the price makes the XFX HD 4770 one of the best video card bangs for your bucks.
