The beginning of March was marked, like each year or almost since good a long time, by the behaviour of the annual edition of CeBIT. In the past living room impossible to circumvent for new technologies, CeBIT in speed, is wedged in the calendar between an international show, and a major European event, the IFA. This phenomenon is not exactly new and the world economic crisis did nothing but accentuate it this year with a particularly morose edition. For proof, the only advertisement of importance, in the graphic map productions, was the exit of GeForce GTS 250, the card which occupies us today.
So formerly CeBIT was used as platform of launching to the manufacturers for new products, it is not more the case today and GeForce GTS 250 is, to be clear as much as of the beginning, only one famous version of GeForce 9800, itself an updated version of GeForce 8800 GTS. It was necessary for us thus to give a progress report on this at the very least unexpected graphics card whose name change leaves think that it is about an innovation in the family of the GeForce chips 200, what is alas not the case. With it all the same an interest?
NVIDIA GeForce GTS 250: new name of G92
We wrote it and repeated, the too ambitious architecture of the chips GeForce 200 does not allow NVIDIA to decline them in versions more economic to produce, as it was for example the case with preceding architectures. It is indeed of use, in the manufacturers of graphics card, to conceive an architecture and to decline it on a whole range of product by adapting various parameters in order to obtain the best compromise performance/price. Only here, with 1.4 billion transistors, the chips GeForce WP 200 are too difficult mammoths with to decrease (note: any analogy with famous remarks would be fortuitous).
Whereas NVIDIA thought its gaining strategy, the renewed and unexpected aggressiveness of AMD with the range of Radeon HD 4000 took the firm with the chameleon of short. The departments research and development of NVIDIA company on the future graphics chip DirectX 11 of the firm, but, while waiting, it is necessary to occupy the ground not to be too much let outdistance in the sales by AMD. For that, NVIDIA appealed, once again, in G92! It is indeed a graphics chip built on famous G92, itself an optimized version of G80 equipping first GeForce 8800, which finds with GeForce GTS 250.
NVIDIA GeForce GTS 250: characteristics and 55 Nm!
You will have included/understood it, no new technical thing is not to be awaited of GeForce GTS 250, if it is not that it is a question of a new supposed name of making it possible NVIDIA to align its quotation with the remainder of its current range. To return from there to the chip, this one benefits from architecture DirectX 10 of GeForce 8 with a total of 128 processors of flow. In order to maximize profitability, one will announce all the same the change of manufactoring process. Whereas the G92 chips animating GeForce 8800 WP, 8800 GTS 512 Mo, 9800 GT/GTX+ are engraved in 65 Nm, always by TSMC, G92 which one finds within GeForce GTS 250 is engraved in 55 Nm. It should thus less heat and less consume that its elder, the surface of the die being indeed reduced.
Graphics chip NVIDIA G92 in 55 Nm: B1 revision
Side of the frequencies of operation, the chip GeForce GTS 250 benefits from frequencies raised vis-a-vis the first models based on G92. One thus finds oneself with a chip operating with 738 MHz for processors of flow turning to 1836 MHz. Side report, we are always in the presence of a bus 256 bits with a frequency of 1100 MHz for the chips GDDR3 which equip the cards of GeForce GTS 250. Small innovation for this model, increase in the memory quantity with 1024 Mo of memory for the model of reference. Partners NVIDIA remain free to propose models of GeForce GTS 250 with 512 Mb or 1 Gb of video memory.
GeForce GTS 250 made by Gigabyte: GV-N250ZL-1GI
Gigabyte is one of the first manufacturers to have been able to forward to us a graphics card based on the processor GeForce GTS 250. Equipped with its own PCB, blue color please, the card moves away very largely from the design of reference suggested by NVIDIA. Exit indeed the radiator double-stage which proposes NVIDIA and place with a cooling system personalized and signed ZALMANN. If the graphics card is adjusted in a simple square, it will occupy all the same two sites in your computer, device ZALMANN being rather cumbersome. Resting on the graphics chip, and only on this one, the system is composed of a broad aluminium tube radiator in the center of which breath a ventilator.

Interfaced in the NCV-Express train 2.0, the card embarks 1 GB of memory GDDR3 distributed on components of Hynix mark. Its power supply is ensured by the bus NCV-Express train, but also by a connector six pins. Equipped with a connector SLI, the card in multi-GPU mode with another card GeForce GTS 250 but also with GeForce 9800 GTX+ can be used, like specifies it the documentations transmitted by NVIDIA.
As for the frequencies of operation, they are strictly identical to those recommended by NVIDIA with 738 MHz for the graphics chip, 1836 MHz for the processors of flows and 1100 MHz for the memory. Let us finish by the exits which one at the very least finds on this card since they are one nothing unusual. Gigabyte indeed proposes a connector DVI, a connector VGA and a connector HDMI. Of what to be able to connect any screen, or almost, without passing by an adapter.
Remain a problem to be underlined, as you can see it on the photographs, the total completion of this card which seems rather average. The cooling system is assembled twisted, whereas the pressure which he exerts on the PCB seems to twist this last. Difficult to say if it is of an exclusive problem to our sample of test or a more general phenomenon.
