The HD 4670 definitely performed well against the geForce 8600GT. Even with AA, the 4670 gave respectable numbers, yes some of them were at the border of playability, but as I already said, you really don't buy a sub-$100 video card expecting to be able to run AA, but if you are willing to tolerate FPS in the 20s, you can get some AA goodness, something not possible with previous "mainstream" video cards.
Of course, if your interests are in video cards costing well over $150, you will probably scoff at the HD 4670, it doesn't perform in the same ballpark.though it does approach performance of midrange cards of the last generation, and outperforms some of them. You must remember, this isn't a "gaming" card, it is a "mainstream" card, intended for the lower-end enthusiast rigs, and upgrades of Dells, HPs, etc.
But can you imagine the performance increase over nominal onboard graphics? This card will make an excellent upgrade for that "store-bought" rig, and with its low power usage, it should be a plug-and-play upgrade for most.
The Sapphire HD 4670's reference cooler was surprisingly quiet, not audible at all.
I found nothing not to like about the HD 4670, considering its price. It's performance far surpassed what I'd expect from that price point. The Sapphire Radeon HD 4670 sells for $79 at my favorite online retailer. That's right, a measly 79 bucks. I never imagined finding a card for that price that would even run AA at all, much less with playable FPS. ThinkComputers.org awards the Sapphire Radeon HD 3670 512MB a 10 out of 10 score.
- A very viable upgrade for off the shelf rigs due to low power usage
- A great choice for low end enthusiast rigs
- Impressive performance for a sub-$100 video card
- A reference cooler that is actually quiet
