Back when the HD 4670 was launched, Sapphire was the first company whose cards we’ve found in retail, and so far, Sapphire managed to launch a couple of cards, one of which is passively cooled. Everyone had high expectations for the HD 4670, especially after rave reviews the HD 4800 generation has received. It was priced at $79/€69, and the price hasn’t changed since.

This card is based on the same architecture as the already famous HD 4870/HD 4850 cards, but it’s aimed at a lower segment, for those seeking for a sub-€100 card. The new architecture brought about a couple of improvements over the previous generation, most notably bad antialiasing gaming performance.

Radeon HD 4670 card has a tough task of proving its worth in a quite densely populated sub-€100 segment. Proving its dominance over the GeForce 9500GT isn’t quite a tough task, but its true adversary is the GeForce 9600GSO, as it costs only a couple of Euros more than the HD 4670 GDDR3. These cards in most cases run neck to neck, but 9600GSO’s couple of Euros more bring a couple of frames more as well. In today’s test, this will be the battle to behold.

Two HD 4670 cards were announced, and they’re different from each other in terms of memory speeds and quantity, and thus in bandwidth. One comes with 1GB of memory running at 900MHz and packing a bandwidth of 28.8GB/s, whereas the other one features a 512MB of memory at 1000MHz. The memory speed on the 512MB version results in a higher bandwidth totaling at 32GB/s.

Apart from the aforementioned HD 4670 cards, another RV730 based card hit the market – the HD 4650. This card, however, uses the GDDR2 memory clocked at 500MHz (1000MHz effectively) and runs slower, at core speed of 600MHz. Note that all the HD 46xx cards are stuck with the 128 bit memory interface.
