Technical data / Specifications
With the TGT GeForce GTX 680 BEAST LLS you get a factory overclocked
card with a close-to-reference PCB design cooled by a huge triple fan cooler. The ASIC quality
measured on our sample was 75.7 %. It's above average but it's
nothing really special.
About ASIC quality:
Looking at clock speeds we see that the GPU runs at 1'163 MHz with a
typical boost of 1'229 MHz. In comparison, the stock designed GTX 680 runs at
1'006 MHz with a typical boost of 1'058 MHz. Like most of the GTX 680 out there
no factory overclocking has been made regarding the GDDR5 memory which stays
clocked at 1'500 MHz (6'000 MHz effective) following nVidia's recommendations.
As surprising as it may sound our card was always running at a fixed frequency
of 1'241 MHz under load. Like there was no boost and the default clock speed was
1'241 MHz just like our DirectCU II Top that was always working at a fixed clock
of 1'201 MHz. We like it!

Looking at specifications, the BEAST LLS is the same card as the
GTX 680 EXO from Point Of View. The PCB seems to follows the
reference design but is slightly different. It's so close to the reference
designed PCB we had in our hand that I believe it's a newer revision of it. POV/TGT added the full number of components
to the power design unlike MSI on the
Twin Frozr OC
for exemple. Therefore you get five phases for the GPU and two for the memory.
The voltage regulation chip is the same like on the "old" reference design:
it's a
Richtek RT8802A.
TGT's graphics card also features two metal plates. The front metal sheet covers the memory chips as well as the power design area
to spread the heat in a more efficient way while the backplate is here so the
card is more stylish you know.
The cooler that keeps this card at adequate temperatures seems to have
certain certain similarities with Arctic's
Accelero Xtreme. We believe this one is being manufactured by Spire. The cooler
has been made from of a copper base plate, five 6mm heatpipes
and a lot of aluminium fins. The fan in the center measures 90 mm in diameter, while the other two
measure 80mm. It is really easy to remove the whole plastic part to clean the entire
cooling block. The left side of the plastic shield has a perfect spot for a logo,
but it was left empty. The manufacturing quality of the cooler is very good even
though the plastic part looks cheap.
TGT chose to attach the cooler with four screws to the card. We tried to move
the cooler from right to left, even applying force didn't help moving it,
which is a good sign. Also the pressure on the graphics core is very good.
The memory chips used, are made by Hynix and carry the model number
H5GQ2H24MFR-R0C. They are specified to run at 1'500 MHz (6'000 MHz effective).
