Sparkle has launched yet another addition to its Calibre series, branded Calibre P890. The new Calibre P890 is based on the G92 8800 GTS card with 512MB of memory. Unfortunately, the new Calibre P890 works at a much lower clock speed than expected.

It is based on the G92 8800GTS GPU which runs at 678MHz, which isn't that much higher than the reference 650MHz clock. The card comes with 512MB of GDDR3 memory working at 1944MHz, which is even more disappointing than the core clock. The Shader clock had a slight bump from reference 1625MHz to 1728MHz but that isn't even close to the 1,825MHz on MSI's 8800GTS which we tested here.

These low clocks can't be blamed on reference cooling, since the MSI card had the same cooling. Some may say that Sparkle shouldn't have used its Calibre series brand, since it was usually reserved for high factory OCed cards and cards with non reference cooling. The bottom line is that Calibre is a good series, but when it comes to the 8800GTS it fails to impress.
