Getting back to the topic of this review, I will again show you a diagram with the recommended and retail prices of the graphics cards. According to the results of the gaming benchmarks (we didn’t take the results of synthetic tests into account here) we calculated the average performance gain for all graphics cards in relation to the lowest-end and cheapest solution of our today’s roundup – Radeon HD 4770. We take its performance as 100% and the speed of all other solutions is shown in percentage to that of Radeon HD 4770 and added to the pricing chart. Here is what we got:
The smaller the difference between the price and performance columns, the better price/performance ratio the graphics card has. Thus, purchasing a GeForce GTS 250 or a Radeon HD 4850 instead of a Radeon HD 4770 is not wise. Switching to a Radeon HD 4870 1GB or a GeForce GTX 260 896MB is more reasonable. The HD 4870 actually seems to be the most optimal buy. The CrossFireX tandem with two Radeon HD 4770 cards is the best of the three top-performance solutions of this test session, but the previous two cards seem to be a better buy than it or than the Radeon HD 4890 1GB or the GeForce GTX 275 896MB. Unfortunately, the noise and power consumption data could not be fitted into the diagram although these factors often determine users’ shopping decisions. Anyway, you can find such data in the body of the review and make up your own mind.
I won’t repeat my summary about the comparisons made in this review (between the Radeon HD 4870 and HD 4890, GeForce GTX 260 and GTX 275) as the diagrams have showed everything clearly. As for the specific cards tested for this review, I can’t single out any of them. The reference Radeon HD 4890 come with standard accessories and could not reach a 1000MHz core frequency at overclocking but the Diamond card is more appealing due to factory overclocking. The HIS Radeon HD 4770 is a cheap and economical product. It would make an ideal low-end card if it had a quieter cooler. The Palit GeForce GTS 250 cards also come with noisy coolers. Moreover, the engineers have implemented queer solutions, equipping one of them with absolutely useless 2GB of memory and reducing the memory frequency of the other. The reference Zotac GeForce GTX 285 can be commended for good accessories and lower noise in comparison with the Radeon HD 4890.
I personally would want to see a dual-processor Radeon HD 4770 X2 with two RV740 chips and with a total of 2GB of memory (1GB per each GPU) and perhaps with increased GPU and memory frequencies (800MHz should not be a problem for this GPU as I have made sure). Equipped with a quiet cooler and priced at $200-220, such a card would make a bestseller.
