GV-N240D5-512I Detailed Features
As I mentioned in the previous section, the low-end 200 series cards are based on NVIDIA's older G92 architecture. This is basically a die-shrink version of the GPU with some tweaking and a few new features. The GeForce GT240 GPU used in the GIGABYTE GV-N240D5-512I video card appears to be based on the 9600GSO GPU: they both have the same number of CUDA cores (96) running at the same clock speed (550mHz). One difference is that the 9600GSO has a 192-bit memory interface, while the card we're testing has to get by with a mere 128-bit memory interface. But remember those "new features"? The GeForce GT240 is NVIDIA's first GPU to support GDDR5 memory, and in this example it's clocked at 1700mHz...so the actual memory bandwidth, at 54.4 gb/second, is much greater than that of the 9600GSO's 38.4 gb/second. The quoted memory bandwidth specification is from the NVIDIA spec sheet, but for some reason GPU-Z shows a memory bandwidth of 108.8gb/second.
After removing the four spring-loaded screws securing the heat sink, we can see the GT215 GPU and the four memory chips:
A close-up view of the GPU reveals its product code, "GT215-450-A2". The "450" in the part number apparently designates this as a DDR5 version.
The 512M of video RAM is comprised of 4 Samsung K4G10325FE-HC05 memory chips modules. These are GDDR5 devices with an access time of 0.5ns.
GIGABYTE extends the NVIDIA reference design for the GT240 with the aforementioned gold-plated HDMI connector and a large 80mm cooling fan. As we'll see later in this review, the 80mm fan does an excellent job cooling the processor.
Full HDMI 1.3a support
Another one of the "new features" is significant for HTPC fans: these are NVIDIA's first cards to support the full HDMI 1.3a standard. Previous NVIDIA GPUs such as the 8200 series have had partial HDMI 1.3a support, but omitted features such as 12 and 16 bit color modes and DTS-HD audio. This, combined with the new cable-less audio support, make this card very well suited for HTPC applications.
In the next section I'll discuss the Benchmark Reviews testing methodology and the test system configuration used in our benchmark evaluation.
