Our GeForce GTX 560 Trio
ASUS ENGTX560 DCII TOP
With a core clock of 925MHz and a memory frequency of 4200MHz DDR, the ASUS ENGTX560 DCII TOP justifies its billing by being the fastest of the three GTX 560 in today's roundup. Equipped with ASUS' DirectCU II cooling system, notable for the dual-fans, copper heatpipes that are in direct contact with the GPU core (hence the name) and an extensive array of heatsink fins, this ASUS card is the heavyweight among the three. We expect great things from this card, based on our experience with the 560 Ti version.
ECS GeForce GTX 560
The slowest of the trio, the ECS GeForce GTX 560 is clocked at the lowest possible clock speed mandated by NVIDIA. This means a core clock of 810MHz, with the memory frequency at 4008MHz DDR. With 1GB of GDDR5 memory, this appears to be a standard configuration for this SKU and ECS has done little to suggest otherwise. The card looks a bit like the reference GTX 560 Ti, though the dual heatpipes on this card appear to be thicker and larger than the reference.
Palit GTX 560 Sonic Platinum
We're not strangers either to Palit's graphics cards, but unlike the 560 Ti Sonic that came with dual fans, this Sonic Platinum only gets a single fan. That doesn't mean Palit has cut back on the clock speeds however, as this Sonic Platinum is still clocked at a speedy 900MHz, with the same memory frequency as the ASUS. Due to Palit's custom PCB, which is shorter than the reference design, this is one card that will fit in cases where space is at a premium.
