The SBM $2550 PC uses the same CPU as Lenovo’s Erazer X700, yet still outperforms it in Sandra Arithmetic by a fairly wide margin. The X700’s 3.9 GHz overclock performs roughly the same as the $2550 PC’s baseline, with XMP memory as its primary differentiating factor. Some manufacturers automatically enable fixed-ratio Turbo Boost mode when XMP is enabled.
To keep a processor within its rated power envelope, the amount of frequency Turbo Boost applies is supposed to decrease as the number of loaded cores increases. Enhanced Turbo sets a fixed boost frequency at the CPU’s highest rated frequency, which for the Core i7-3930K is 3.8 GHz.
Memory performance coincidentally scales in proportion to price. The expensive systems have quad-channel memory controllers, while the mid-priced builds are stuck with two channels.
HD 8XXX cards are rebranded 7XXX cards for OEMS to use for marketing, cause you know, uninformed Consumers love to think that larger number means better and that new products(despite not really being new) convinces them to buy it. an 8950 should be a rebranded 7950
