![]() But you could save some money going with the Single-Core - and have enough left over for a better graphics card. If you are upgrading from a G4 Power Mac and you are trying to decide between a "close-out" or refurbished Single Core and a new Dual-Core (both running at the same clock speed), you aren't giving up any performance to choose the Dual-Core. (* Though the 9600 XT should be running at 500MHz, Apple clocked theirs at 400MHz, making it a 9600 Pro in reality.)ĭon't forget to see our comparison of the Quad-Core G5/2.5 Power Mac with the Single-Core Dual G5/2.5 Power Mac. FYI, here are the specs on the cards we used in this particular test session: It's a tough call as to which graphics card is most fair in the comparison since we can't really run identical cards on both systems. When it comes to OpenGL 3D accelerated games, the Dual-Core beat the Single-Core two out of three - until we added the Radeon 9800 Pro SE to the Single-Core. The Dual-Core easily beat the Single-Core until we added the 9800 Pro SE. ![]() The Dual-Core with the GeForce 6600LE and the Single-Core with the Radeon 9600 XT represent typical configurations for those two platforms. However, with the trend toward utilizing the graphics processor to help with rendering, you have to take the graphics card into consideration in the Motion and iMaginator graphs. The 1MB L2 cache in each of the Dual-Core's processors doesn't hurt. On strictly CPU intensive tasks (top three graphs), the single Dual-Core G5/2.0GHz Power Mac was as fast or faster than the dual Single-Core G5/2.0GHz Power Mac.

One of the questions asked most often is, "Assuming both are running at the same clock speed, will a dual single-core G5 Power Mac go faster than a single dual-core G5 Power Mac?" Last week we got our hands on a Dual-Core G5/2.0GHz Power Mac to compare to our dual Single-Core G5/2.0GHz Power Mac. We've received many questions regarding the new Dual-Core G5 Power Macs. ![]()
