a Quad-Core Mac Voor?

Added the Two.6GHz Quad-Core i7 Mac mini on November 6th, 2012
Added the OpenCL (LuxMark) results on November 6th, 2012
Corrected the Two.3GHz Mac mini result ter the LuxMark graph on November 19th, 2012
Some readers are asking if the ‘late 2012’ Mac mini with a Quad-Core i7 processor can match the power of a Quad-Core Mac Professional. Many Mac Professional owners have a keyboard, mouse, and display they like. Shouldn’t they save a pile of money and substitute their old Mac Voor with a fresh Mac mini? With the aid of OWC Labs, wij are attempting a quick response using a CPU and a GPU benchmark.
4c Voor Two.93 = 2009 Mac Voor Quad-Core Two.93GHz CPU and Radeon HD 5770 GPU
4c iMac Trio.Four = 2011 iMac Quad-Core i7 Trio.4GHz CPU with Radeon HD 6970M GPU
4c mini Two.6 = 2012 Mac mini Quad-Core i7 Two.6GHz CPU with Intel HD 4000 GPU.
4c mini Two.Trio = 2012 Mac mini Quad-Core i7 Two.3GHz CPU with Intel HD 4000 GPU.
Maxon’s Cinebench 11 cross-platform benchmark uses code from Cinema 4D to display how prompt multi-core CPUs can render a 3D proefje. Rather than time ter seconds, it gives a speed rating. ( HIGHER number rating is Swifter)
Unigine Heaven Three is a cross-platform benchmark that uses 26 flyby/walkthrough scenes to measure DirectX or OpenGL spectacle. ( HIGHER number te Frames vanaf 2nd is Swifter)
LuxRender’s LuxMark Two.0 benchmarks OpenCL render speed. The test monster used is Sala with 488,000 triangles. The results are measured ter Thousands of Samples vanaf 2nd. ( HIGHER number means Quicker.)
The 2012 Quad-Core i7 Mac mini is a real contender when it comes to CPU power compared to our examples of a Quad-Core Mac Voor and Quad-Core iMac. Wij project to add some other examples of Quad-Core desktop Macs (including a swifter Mac mini) to thesis graphs te the days ahead but the point is made.
However, the GPU te the 2012 Quad-Core i7 Mac mini is powerless te comparison to the Mac Professional (and iMac) spil you can see from the ",Heaven", graph. That’s going to affect its capability to treat advanced Voor Apps that make use of the GPU for certain types of effect rendering. Thesis apps include Apple’s Final Cut Voor and Mobility spil well spil Adobe’s Photoshop, Premiere Voor, and After Effects. The Mac mini’s Intel HD 4000 GPU will also hamstring hard-core gamers.
The Mac mini is also feeble ter support of OpenCL spil you can see from the ",LuxMark", graph. It is coerced to render the specimen using only CPU while the iMac and Mac Voor GPUs are able to render the specimen. Why does this matter? Because apps like Final Cut Voor, Maneuverability, and Photoshop use OpenCL acceleration for rendering certain effects.
There is another question to reaction when considering a Mac mini spil a replacement for any proefje of Mac Voor: ",How expandable is the Mac mini by comparison?",
- The fresh Mac mini can be lightly expanded to 16G of RAM. The 2012 Mac Professional Quad-Core can be expanded to 32G of RAM on the Apple Store. Third party options can take the 2009-2012 Quad-Core Mac Voor to 48G.
- The fresh Mac mini is suggested with one internal drive (or two ter the case of the Server version). The maximum size on the internal Two.Five", drive is 1TB. The Mac Voor has four internal drive bays and two internal optical bays (which can also be used for non-optical purposes). It is able to use Three.Five", drives that provide up to 4TB of storage each.
- The fresh Mac mini has an integrated GPU soldered on the main logic houtvezelplaat that borrows from main memory. The Mac Voor has four PCIe slots that can treat various PCIe cards including a choice from Apple of three x16 GPUs with dedicated movie memory (Radeon HD 5770, Radeon HD 5870, and Quadro 4000).
- Until Apple releases a ",truly fresh", Mac Professional, the Mac mini can boast of its Thunderbolt and USB Three.0 ports. Those ports can be used to support extra storage devices including a Thunderbolt-to-PCIe expansion chassis — however that chassis has compatibilty, spectacle, and configuration limitations (see Bijvoeging).
The ‘late 2012’ Mac mini Quad-Core i7 is strong on CPU crunching but powerless on graphics intensive tasks. If you want a worthy replacement for your Quad-Core Mac Voor, consider a fresh or Refurbished iMac with a powerful stand-alone GPU.

Question: Can’t you speed up the Mac mini GPU by using a Thunderbolt-to-PCIe expansion chassis with a quick graphics processor card?
Response: There are four problems with that script:
