The EVGA GeForce GTX 460 1GB SC is overclocked from the standard NVIDIA reference 460; the core clocks are increased from 675MHz core and 900MHz memory to 763MHz core and 950Mhz memory. While this seems a small increase, it is effectively larger as both the shader clock and effective memory rate are driven by these clocks - doubled and quadrupled, respectively.
EVGA GTX 460 1GB SC
The card design itself closely follows the NVIDIA reference layout and cooler. Its a svelte and compact card, similar in size to a HD 5770, much smaller than the previous generation GTX 260 it could be contrasted with.
GTX 460 Processor
EVGA offer their Step Up program on the GTX 460 SC 1GB, allowing purchasers to setup to a higher card for only the difference in MSRP. This offer is valid for 90 days from the purchase of the first card. EVGA offer four levels of warranty support. The levels are 2 year, 3 year, 5 year and lifetime, and are applied to different products. You can find full details here. As the product code for this card is ends in -AR, it is eligible for lifetime warranty support provided you register the card within 30 days of purchase. If you don't register your card, you get 1 year.
EVGA offers a lot of value with the purchase of their cards. Included with the GeForce GTX 460 are downloadable games Cryostasis and Metro 2033. With the card itself are two dual 4-pin molex to 6-pin PCI-e power adapters, in case your 450W or higher rated PSU doesn't have the requisite outputs on its 24A 12v lines. You also get a nifty case badge plus a large side panel sticker, as well as two output dongles - one for mini-HDMI to full HDMI, and DVI to VGA. You can also download EVGA 11th Anniversary wallpapers here.
EVGA Accessories Bundle
The enclosed CD also includes utilities and drivers to get you started. A nice feature of the box is the window to the actual serial number. This allows you to see if the box number and the card number match up, so you can be sure what's on the box is inside.
Fermi GF104 Core
NVIDIA's GeForce GTX 460 is based on the Fermi architecture debuted with the GTX 470 and 480. However, the basic building block - Graphics Processing Cluster - is of a slightly different design here than in the codename GF100 core based cards. It's also a different shape; its 332-367mm2 core is rectangular and fitted with a tasty large heat spreader.
NVIDIA 'Fermi' Architecture Codename GF104
The GF104 features eight Streaming Multiprocessors (SM). Each SM is comprised of 48 CUDA cores and four dispatch units, and a Polymorph Engine. The Polymorph engine is the dedicated hardware used for (amongst other things) Tessellation. The more Polymorph engines, the more tessellation power. The five stages in the Polymorph engine send their output to the shaders for processing, before finally sending to the Raster Engine.
The GF104 in the GTX 460 has 7 of the 8 SM's enabled. In the GTX 460 1GB, this means a 256-bit memory bus, 56 Texture Units and 32 ROP's. The 460 768MB model still has the same clocks and CUDA core count, but 384KB L2 cache, 24 ROP's and a 192-bit memory interface. That's quite a big difference for a box differentiation of only the VRAM amount.
