The GT 220 (this one from Palit) is meant to fill the void in nVidia's product stack between the 9500 and 9600GT. The GT 220 is built upon a 40nm process and the core has 48 Cuda cores (processing cores), eight ROPs and 16 texture units. For memory, the GT 220 comes equipped with 512MB of GDDR3 memory on a 128-bit bus. As a Sonic Edition card, the Palit GT 220 has the expected clock speed increase from the base 625MHz on the core all the way up to 720MHz with the Shaders getting a bump from 1380MHz to 1566MHz, while the 512MB of GDDR3 memory gets a bump to 900MHz. Each bus is overclocked to offer an increase in both computing and graphics performance. The GT 220 is DX 10.1 and Shader model 4.1 compatible. The GT 220 is a scant 5.5 inches long and should easily fit in just about any chassis out there with no problems. Palit has chosen to use OS-Con capacitors for long term reliability.
The Palit GT 220 offers up three ways of connecting to your display, Dual Link DVI, D-Sub, or a native HDMI connection. This will offer a way to carry both the sound and picture to your high-def television. Along the back end of the card it appears that there is something missing, but is it? This card does not need an external power connection and power is fed entirely through the PCI-E x16 slot. The power specification for this card is 58 watts under load and seven watts at idle. The heatsink assembly covers half of a few memory modules but the heatsink does not provide any direct cooling as there is no contact.
When you pull the heatsink off you can see that there are only four memory modules on the front side of the PCB with the other four on the back side. The core reads GT216-300 revision A2. The memory used on the Palit GT 220 is made by Qimonda and is designed to operate at speeds up to 1000MHz, depending on the internal Cas latency, with 1.8volts.
The heatsink assembly is a small aluminum finned block that sits directly on the core and is held in place with four spring loaded screws. The fan used is made by Power Logic and is 60mm in diameter. The fan was silent during operation and allows the GPU core to operate below 60 degrees Celsius when overclocked and under load. Not too bad for a graphics card today, but when you consider that the GT 220 uses only 58 watts when at the stock clocks, you really don't need a huge, beefy heatsink.
This card is meant more as a co-processor than an out and out gaming powerhouse, so let's see what it holds in store for us.
