techPowerUp posted a review on the Club 3D HD 7870 jokerCard Tahiti LE 2 GB graphics card
Among the only AMD board partners that opted to make cards based on this chip, which has been codenamed "Tahiti LE," are ones that rely on contract manufacturer TUL corp., these include Club3D, PowerColor, and VTX3D. The latter two are even owned by TUL. Today we have with us Club3D's contraption, called HD 7870 jokerCard, part of its Poker Series.
AMD's new GPU is called "Tahiti LE" even though it's positioned inside the Radeon HD 7800 series, because its derived from the 3.5 billion-transistor "Tahiti" silicon, the same one that goes into making all Radeon HD 7900 series products, and not the "Pitcairn" silicon, which goes into making the HD 7870 GHz Edition and HD 7850. The new SKU drops the "GHz Edition" moniker, because it features lower clock speeds than the HD 7870 GHz Edition, but makes up for that with more pixel-crunching muscle.
The HD 7870 "Tahiti LE" is carved out of the Tahiti silicon by disabling a fourth of its Graphics CoreNext clusters, resulting in a stream processor count of 1,536, a texture memory unit (TMU) count of 96, and raster operations processor (ROP) count of 32. The memory bus width is reduced by a third, it is now 256-bit wide, and holds 2 GB of memory. The new chip features PowerTune with Boost, a dynamic core overclocking equivalent to NVIDIA's GPU Boost. The card ships with GPU clock speed of 925 MHz, PowerTune boost clock of 975 MHz, and 6.00 GHz memory, resulting in a memory bandwidth of 192 GB/s.
