Radeon HD 3650 Showdown - ASUS vs. HIS

0 thumbs up


Just last week, we posted an evaluation of a Radeon HD 3650 card by Diamond Multimedia, where said manufacturer decided to one-up ATI's reference specifications by raising the amount of on-board memory to a full one gigabyte.  The results, unfortunately, were not overly favorable as the memory happened to be of the inexpensive, low-speed DDR2 variety.

Today, however, we take a look at two more HD 3650s, one each from ASUS and HIS, where the emphasis was placed more on clock speeds than on memory buffer size.  While the default speeds set forth by ATI's reference specifications were listed as 725 MHz for the GPU core and 800 MHz for the memory, the two cards represented in this article are decidedly faster: 800 / 900 MHz for ASUS and 790 / 890MHz for HIS.  The 10 MHz variance is not the only thing that separates the two cards, however.  ASUS' EAH3650 TOP comes with the standard 256 MB frame buffer, whereas HIS doubles this to 512 MB on their Radeon HD 3650 IceQ Turbo.  One card has slightly higher speeds, the other has twice the memory - let's see who wins this showdown of overclocked Radeon HD 3650s.

ASUS                                                    HIS

With the Radeon HD 3650 marketed as a low-cost alternative for gaming on a budget, it's no surprise that each card's accompanying accessories are a little light.  Each company includes a multi-language user's installation guide and a drivers CD, and ASUS also provides a digital copy of the guide on a second CD-ROM as well.  To cover the various setup options, each card also ships with a single VGA-DVI adaptor and an additional HDMI-DVI adaptor.  The major difference between the two bundles comes down to a single cable.  ASUS plays it safe by offering one last S-Video connection cable.  HIS, however, hope users may choose to purchase a second card, thus needing the CrossFire bridge found here.  HIS also throws in a case badge for good measure.

i dont find any of these cards to be playable at settings that high. 15 fps tops for company of heroes? 11.67 fps tops for crysis? i dont think people who buy the 3650 are looking for high quality high res gaming. i think it would of been better to have tests in both high quality and medium.

For the sake of comparison with other articles, we like to use the same high-quality settings across the board. HH readers are savvy enough to know that using lower-quality settings will result in higher performance. It's the relative performance between products that's important to consider.

Hehe, look at them all get spanked by Crysis.Stick out tongue

ATi's 3650 line isn't too competitive.  The aging 8600GT line is a better option, imo.  Even the 2600XT often outperforms the 3650 by a smidge.
