How popular have AMD's new Radeon HD 4800-series graphics cards become? Pretty popular, judging by sales numbers from market research firm NPD. TG Daily says the numbers show a Visiontek Radeon HD 4850 sitting at the top of the retail sales charts for September.
Nvidia didn't exactly do poorly in the same month, though. A PNY-branded GeForce 8500 GT came in a close second with 4,106 unit sales (compared to 4,197 for the Radeon), and Nvidia-based cards accounted for seven of the top 10 spots. In terms of sales numbers, GeForce cards made up about 69% of the 31,000 or so graphics cards from NPD's top-10 list, while Radeon HD 4850 and 4870 offerings filled in the remaining ~32%.
Beyond simple market share struggles, a close look at the NPD figures shows interesting facts: for instance, only four of the top-10 cards cost less than $100 before rebates, and only one has a price tag higher than $200 (a Visiontek Radeon HD 4870). Also, none of these cards have more than 512MB of memory, suggesting users aren't always lured by low-end cards with insane amounts of memory.
