The NVIDIA GeForce GTS 450
At the tail of two powerful predecessors--GeForce GTX 480 and GTX 460--a new card estimated around £110 does not seem to thrill much. Or does it?
Having only one Graphics Processing Cluster (GPC) consisting of four Streaming Multiprocessors (SMs), Nvidia’s GTS 450 is the most basic Fermi GPU there is yet. It is basically half of its predecessor GTX 40 with two GPCs, if you think of it. Its dynamics works one raster-setup and four vertex operations per clock, as it has only one Raster Engine and four PolyMorph engines. Double that dynamics and you get the per-clock operations of the GTX 460. But the new card offsets the equation by running at high frequencies: the core at 783MHz and the GPC at 1,566MHz.
The tested GTX 460 has a revised stream processor layout that the GTS 450 on trial employs, that which includes 48 units in one SM instead of the 32 units per SM that the GTX 480 and GTX 470 have. 192 stream processors hulk the hundred-pound GeForce card, way heftier than that of the GTS 250 that it has been designed to surpass.
The new cards should be aimed at dual slots requiring one 6-pin power connections, the reference PCB being 8.25 inches and uses up to 106W at the most.
This makes for an appeal to home-entertainment-performance enthusiasts, such as HTPC users, as GTS 450 allows bit-streaming for Dolby True HD and DTS-HD Master Audio using its mini-HDMI output.
