GTX 580 – Voltage and current monitoring chips, labelled U14, U15 and U16 To shorten the story, NVIDIA uses a mix of hardware monitoring chips AND FurMark detection at the driver level to limit the power draw. Memory: 1536MB GDDR5 1002MHz real clock (or 4008MHz effective, see Graphics Cards Memory Speed Demystified for more details), 384-bit bus width. Now we have the explanation of this strange FurMark screenshot. In short, when FurMark is detected, the GTX 580 is throttled back by the power consumption monitoring chips. And still like AMD with the Catalyst drivers (see FurMark Slowdown by Catalyst Graphics Drivers is INtentional!), there are somne optimizations in ForceWare R262.xx when FurMark (or OCCT) is detected (hehe, maybe the weak link?). Like AMD with the Radeon HD 5000 series (see )ATI Cypress (Radeon HD 5870) Cards Have Hardware Protection Against Power Virus Like FurMark and OCCT), NVIDIA has added dedicated hardware to limit the power draw. For more detail about new things brought by the GF110, check this page out.īut the real new thing is somewhere else: the power draw is now under strict control. This card is powered by the GF110 GPU, which is a refresh of the GF100 GPU. ! updated: ZoomGPU 1.36.NVIDIA has officially released the successor of the GTX 480: the GeForce GTX 580. + updated detection of some Radeon RX 480/470/580/570. + added detection of Intel Arc A770 and A750. + added support of GeForce RTX 4090 and RTX 4080. ! updated: ZoomGPU 1.36.1 (GPU monitoring library) * fixed a bug in the detection of AMD Radeon GPUs. It's a quick OpenGL benchmark as well (with online scores).
