GeForce GTX 275

The reasons for the appearance of the GTX 275 can be described by the well-known proverb “no place will be empty”: firstly, the niche between the GTX 260 and GTX 285 was not occupied, and secondly, none of these cards are suitable for the title of rival to the Radeon HD 4890 - the first is too weak, the second is too expensive.

 

There was a need for an inexpensive accelerator that could confidently compete with the HD 4890. NVIDIA did not invent something new, but slightly changed the GTX 285, resulting in the GTX 275.

There are few differences from the flagship line of single-chip video cards. The memory bus has gone under the knife - instead of 512 bits in the GTX 275 it is 448 (the same as in the GTX 260), controllers that have become “unnecessary” and part of the ROP are disabled, and, of course, the number and total volume of GDDR3 chips has decreased slightly , soldered on the board.

 NVIDIA successfully completed the task - to create a worthy rival to the Radeon HD 4890. In fact, Californians have taken a number of measures to reduce the price of the GTX 285 by $70-90 without harming themselves. As for the lost megabytes of video memory and damaged bits of the memory bus, they can be easily compensated for by overclocking - even with a standard cooling system, the video chip can easily overclock to 720-750 MHz. Of course, you can’t increase the amount of memory by raising clock speeds, but the missing 128 MB almost never plays a decisive role.
