Inno3D GTX 460 1GB OC Review


Closer Look:

The Inno3D GTX 460 is built around the GF104 core that is made on the same 40nm fabrication process as the earlier GF100 Fermi cores. Since the transistor count has dropped nearly a billion, the core size has also decreased significantly, which means increased yields per wafer for NVIDIA and a less expensive video card for consumers. Size also plays a role with power consumption, heat output, and number of yields during creation since the larger a core, the harder it is to make reliably. 48 CUDA cores are paired per streaming multiprocessor and the GF104 has eight SMs, but on the GTX 460, only seven are enabled. Depending on if they were physically disabled or not, they may be unlocked, and likely points to a future card with all eight enabled with a total of 384 cores. The GTX 460s come with either 192-bit or 256-bit memory buses combined with 768MB (6x128MB) or 1GB (8x128MB) of memory, respectively. Reference clocks put the GTX 460s at 675MHz core, 1350MHz shader, and 900MHz memory speeds, while the Inno3D is factory overclocked to 750MHz core, 1500MHz shader, and 950MHz memory.

The artwork on the plastic shroud is very similar to that on the packaging, but without the refracting. The impeller is translucent in a smoky color, while the shroud is black and opaque. Only four screws with springs and plastic washers are used to mount the heat sink to the core - other holes are empty, but are placed around the card and should make it easy to water cool. One important thing for interested consumers is that the GTX 460 is only capable of 2-card SLI since each GTX 460 has only one SLI connection.
















The Inno3D GTX 460’s size is much smaller (at 8.25" length) than many of the behemoths of late, such as the ATI 5800s and first generation NVIDIA Fermi cards. The sides of the card are blank and clean, and the whole shroud allows air to escape into the case and through the expansion slot grilles. The thickness is only two slots worth - typical for most mainstream solutions - so fitting this inside most cases shouldn’t be difficult at all. This card should be installed into a PCI Express x16 slot for it to be able to take advantage of full bandwidth.



The GTX 460 provides digital output through two Dual Link DVI outputs and an HDMI port. The back of the graphics card is open enough for air to escape and even to catch another glimpse of the heat sink fins. Both of the 6-pin PCIe power connections are located on the back furthest away from the PCI Express slot. The fan used is a PWM-style, four-wired fan.



The single SLI connector means that only two GTX 460s may be used in SLI together in normal settings. The pins look like they may be gold or gold-plated, which would help keep them from oxidizing. Dual 6-pin PCIe connectors are installed on the GTX 460s to ensure that there is more than enough energy even after overclocking. Both connectors are near the top of the graphics card, away from the PCI Express slot.
