How would the number of transistors affect the performance of a graphics card? Most reviews relate the core and memory frequencies to performance. But how about the number of transistors? Let's have a look at two Sapphire cards: HD 2600 PRO HD 2400 PRO process (Die size) 0,065 µ 0,065 µ transistor count 390 Mio. 180 Mio. memory options 256 MB 256 MB Core frequency 600 525 Memory frequency (eff.) 1000 800 Well, they have similar clock frequencies, and both use DDR2 memory, but an HD2600 has twice the number of transistors of an HD2400. So, same question again, how does the number of transistors affect the performance of a graphics card?
