HIS HD7870 IceQ Turbo and IceQ X Turbo X Review

For overclocking today we are using Catalyst Control Center.

Both cards overclock well, with the IceQ X Turbo X reaching a 1,240mhz core clock speed. Very impressive. Both cards achieve at least a further 10% on the core clock. The GDDR5 memory can be pushed to 1,400mhz+ on both cards, which is an effective speed of 5.6Gbps (5.76Gbps on the Turbo X).

The cards respond very well to overclocking, falling in slightly behind a reference clocked HD7970. This is very impressive, especially when considering the price differences between the ranges.
