Geforce GTS 250 reviewed: Three new graphics cards put to test
The Geforce GTS 250 is Nvidia's latest creation and the next Geforce graphics card with a G92b chip that enters the competition with AMD/Ati. We checked the GTS 250 and took a look at the innovations delivered by the card.
Geforce GTS 250 - Performance review: Introduction and Technology
Right on the beginning of the Cebit trade show Nvidia presents the Geforce GTS 250. The graphics cards is, like many previous devices, based on the G92 architecture and thus is similar to the 9800 GTX+ in matters of technical specifications. So those who expect a GT200 related GPU because of the name will be disappointed.
Until the weekend before the Cebit we did not receive any samples of the new card and thus could not run a new benchmark array before the Cebit. But this isn't a real problem since the technical specifications (except the memory timings possibly) don't differ from those of the Gigabyte Geforce 9800 GTX+ which we tested with the frequencies of the GTS 250. So for once the performance is simulated and because our tight schedule (Cebit preparations and deadline for our print magazine) we don't use the latest drivers.
As a small compensation we recorded the three estimated clock speed versions so that you get an impression of the performance delivered by cards that are not overclocked.
Please pay some attention to the new presentation of our benchmarks. Above the result chart you can select the desired resolution by clicking the appropriate settings.
Innovations of the GTS 250
There are some differences between the 9800 GTX + and the GTS 250 but those are not related to the performance of the graphics cards. According to Nvidia the GTS 250 with 1 GiByte VRAM is sold to the board partners for the same price as the 9800 GTX+ with 512 MiByte. Soon there is supposed to be a 512 MiByte version that will cost about 20 to 30 Euros less - thus the new card more or less represents a price cut and reaches a similar price level as the still lower priced Radeon HD 4850.
Nvidia also made an effort in overhauling the board design. The Geforce GTS 250 bears a strong visual resemblance to the 8800 GTS, but differs in at least two important points. First there are two SLI connectors - like on the 9800 GTX(+) - so the card will most likely support 3-way SLI. Furthermore the use of 55 nanometer G92b chips lowers the power consumption resulting in a 150 watt TDP issued by Nvidia. Accordingly default design of the GTS 250 has only one 6-pin power connector which has been relocated and is now directed to the upper side of the card.
