Nvidia 9800 Gt 1gb Specs

[Alexia Borson]

Avery smart man at Intel once told me that when designing a microprocessor you can either build a new architecture, or move to a smaller manufacturing process, but you don't do both at the same time. The reason you don't do both is because it significantly complicates the design, validation and manufacturing processes - you want to instead limit the number of variables you're changing in order to guarantee a quick ramp up and good yields of your silicon.

NVIDIA followed this rule of thumb with the GT200, building its "brand new" (or at least significantly evolved) architecture on a tried-and-true 65nm process instead of starting at 55nm. Despite AMD building both RV670 and the new RV770 GPU on TSMC's 55nm process, NVIDIA hadn't built anything on a smaller than 65nm process, including the 1.4 billion transistor GT200.

Originally we thought the GTX+ was a silly last minute afterthought as it looked like nothing more than an overclocked 9800 GTX. While its clock speeds are higher, it also happens to be the very first 55nm NVIDIA GPU. The specs are as follows:

The core clock went up 9.3%, shader clock went up 8.6% and memory clock stayed the same. The clock speed bumps are marginal and by far the more interesting aspect of the chip is how much less power it consumes thanks to its 55nm process, which thanks to AMD should be quite mature by now.

Notice something very wrong? The 8800 GTS 512 and 8800 GT both need to drop in price significantly, they are simply uncompetitive at their current price points. I expect one of those two products to go the way of the dodo but it's unclear which one; the 8800 GT is cheaper to make, but perhaps it's easier to produce 65nm parts with 128 SPs so the GTS 512 could stick around at a lower price point as well.

When we think about ECS and their product lines, we typically expect a budget-minded approach. Solid products at reasonable prices that don't exactly wow the consumer, but don't hit them hard in the wallet either. The ECS X48T-A motherboard that we looked at a few weeks ago was one of the first steps by ECS to change that image, although a few missteps with the construction as well as some overclocking issues didn't overly sway us to their new way of thinking.

Thus, we were a bit surprised when we first heard about the ECS GeForce 9800 GTX+ Hydra - a twin pack of high-end graphics cards consisting of two GeForce 9800 GTX+ cards combined with liquid-cooling. The 9800 GTX+ is the upper level of the 9xxx series, with the plus denoting an extra bump in the clock speeds to get better peformance in the most demanding applications. Two of these used in an SLI configuration would be a gamer's dream, although the noise and heat output could be an issue. ECS has solved these problems by providing the customized liquid cooling unit from ThermalTake using the BigWater 760is. ECS hopes to make a big splash here with the Hydra pack, possibly the first of its kind to include all three components in one box. First, we'll take a look at the specs of the GeForce 9800 GTX+ and then move onto a closer look at ECS' take on it and finally the BigWater 760is.

Hello to all,

I plan on purchasing the nvidia geforce 9800 GT for CUDA development. As I understand this card requires that power should be

directly supplied to the graphics card. However in the environment that I hope to use the graphics card I will not be able to provide the

external power. Will this have any effect on the CUDA programs, performance wise or will any other issues come up ?

The soon to be released GeForce 9800 GT has surfaced on the web, well at least a photo and some information. A while ago we already spotted the XFX version, it seems that once sample from ECS got leaked and this time with some more information on it.

The GeForce 9800 GT seems to be nothing lese than a rebadged 8800 GT, with slightly different specifications. It will be have 112 Shader processor-enabled, still be based on the 65nm G92 GPU and have the same frequencies and specs as the 8800 GT counterpart. The one thing that did change is that Nvidia's board partners can play around with a customized PCB and choose to make something really special.

The card shown below is made by ECS and is cooled by Arctic Cooling's Accelero S1. It features a blue PCB and GPU, shader and memory frequencies of 600, 1500 and 1800 MHz. The card has 512MB of GDDR3 memory, a 256-bit interface and DirectX 10(.0) and SLI support.
