GeForce 7100GS, 7900GS i 7950GT
nVidia is set to release three new products in the coming weeks to do battle with ATi during the holiday season. This time around nVidia is launching new mid-range and entry level offerings to take on ATi’s recently launched Radeon X1300XT, X1650 Pro, X1900XT 256MB, X1950XTX and X1950 CrossFire. nVidia’s new offerings arrive in the form of the GeForce 7100GS, 7900GS and 7950GT.
At the entry level side of things nVidia is replacing its GeForce 6200TC with a new GeForce 7100GS. The G72 based 7100GS retains Turbo Cache support like the GeForce 6200TC it replaces. There will be 128MB of onboard memory which translates into 512MB effective memory with nVidia’s Turbo Cache technology. The GeForce 7100GS is also backed by a 64-bit memory interface with compatibility with DDR2 memory. Four pixel shader units are available on the GeForce 7100GS. Core clock of the GeForce 7100GS is set at a rather conservative 350 MHz. nVidia SLi and PureVideo technologies are supported by the GeForce 7100GS, though it lacks the SLi bridge connector.
Moving up is the retail nVidia GeForce 7900GS. Previously the GeForce 7900GS was only available as an OEM offering from system manufacturers such as Dell. Woot also had OEM versions of the MSI GeForce 7900GS for sale at $139 a pop a couple days ago as well. Specifications for the retail GeForce 7900GS are identical to the OEM versions. A 450 MHz core clock is joined by a 1.32 GHz memory clock. It’s also equipped with 20 pixel shader units and 256MB of graphics memory. Support for HDCP is dependant on individual graphics card manufacturers.
Dell has been selling the 7900GS in its XPS systems for some time, but you cannot buy the cards individually.
At the upper spectrum of nVidia’s mid-range lineup is the GeForce 7950GT. Sporting a 550 MHz core clock and 1.4 GHz memory clock the GeForce 7950GT is a successor to the previous GeForce 7900GT. Memory size has increased to 512MB with the GeForce 7950GT. The GeForce 7950GT will also have 24 pixel shader units like the previous GeForce 7900GT. HDCP compliance and dual dual-link DVI outputs are standard on all GeForce 7950GT cards as well.
SLI technology is supported on the GeForce 7900GS and 7950GT. Availability of GeForce 7100GS, 7900GS and 7950GT cards are expected in the first half of September for for less than $100, $199 and $299 respectively.
