[XC] Oj101 from Xtremesystem have post some new relative numbers for 7950 vs 7970.. ofc thoses are just indicative.

Instead of posting another thread, I'll build on this one. This is exclusive to FlyingSuicide and out of respect for the wishes of the person who showed me I won't publish the exact figures.

While many crave for Radeon HD 7970 performance but can’t afford it, AMD has the answer with the Radeon HD 7950 which offers slightly lower performance at the lower price point of US $449 which should soon drop to US $399. With the unified shader count dropped from 2048 to 1792, the TMU (Texture Mapping Unit) dropped from 128 to 112 and the ROP (Render OutPut unit) count staying at 32, the HD 7950 is a moderately crippled HD 7970.
Clock speeds on the Radeon HD 7950 also take a hit from 925 / 5,500 MHz (1,375 MHz actual) for the core and memory speeds respectively down to 800 / 5,000 MHz (1,250 MHz actual), one may be forgiven for thinking that the HD 7950 will be a good deal slower than the HD 7970. However, this is not the case. Unified shader and TMU count, along with core speed, have dropped about 14% and this translates to almost exactly a 14% drop in performance as seen exclusively by FlyingSuicide. We will respect the wishes of those who showed us the card to not give exact figures but rather percentages.

As the 7950 have lower clock speed of the 7970 ( 800mhz vs 925mhz), clock to clock and oc models, should end even end closer of the 7970 in games.
