GIGABYTE BRIX Pro: A Second Look at the Intel i7-4770R with Iris Pro HD 5200
by Ganesh T S on June 14, 2014 5:00 PM ESTPerformance Metrics - I
The BRIX Pro was evaluated using our standard test suite for low power desktops / industrial PCs. We have recently revamped our benchmark suite (after the publication of the Intel D54250WYK NUC review). We reran some of the new benchmarks on the original configuration also, but some of them couldn't be run on loaner samples. Therefore, the list of PCs in each graph might not be the same.
Futuremark PCMark 8
This is one of the new tests in our test suite. PCMark 8 provides various usage scenarios (home, creative and work) and offers ways to benchmark both baseline (CPU-only) as well as OpenCL accelerated (CPU + GPU) performance. We benchmarked select PCs for the OpenCL accelerated performance in all three usage scenarios.
Miscellaneous Futuremark Benchmarks
3D Rendering - CINEBENCH R15
We have moved on from R11.5 to R15 for 3D rendering evaluation. CINEBENCH R15 provides three benchmark modes - OpenGL, single threaded and multi-threaded. Evaluation of select PCs in all three modes provided us the following results.

RAM speeds have a BIG impact on the performance of IGPs, both for Intel and AMD. Speed is even <a href="http://www.anandtech.com/show/7364/memory-scaling-... important</a> than Latency.Hrel - Monday, June 16, 2014 - link
Except that paying for that "faster" RAM costs you money and yields no tangible benefit beyond 1866. The price/performance sweet spot is 1866.http://www.anandtech.com/show/7364/memory-scaling-...

"you can easily get 2133 for a decent price" You've seen the photograph, with SoDIMMs? Where do you buy 2133 MHz SoDIMMS for a decent price?TwistedKestrel - Saturday, June 14, 2014 - link
I don't understand how graphics performance is worse if the RAM in the (2) is faster in every way. Even if you didn't use the XMP profile, it should still be faster!TwistedKestrel - Saturday, June 14, 2014 - link
I meant to say, worse in ANY scenario. The (2) should win out every time, not just some of the time.ganeshts - Saturday, June 14, 2014 - link
In areas where they are close or (1) wins out, the error is within measurement margin, but in the gaming scenarios where there is a big difference, (2) wins handsomely.Some benchmarks are also not dependent on the memory (CPU-bound).

It might be worth investigating whether the crystal well gpu can decrease CPU throughput when it is heavily taxed. That would explain why giving crystal well more memory bandwidth slightly decreases CPU performance. Although they are separate parts of the die, they communicate across the same bus and are flip-chip limited.etamin - Saturday, June 14, 2014 - link
My guess is that the difference is more related to thermals than RAM. Intel iGP's are less dependent on DRAM speeds than AMD's, especially the Crystal Well parts. Outside of the one Tomb Raider benchmark at 1080p, the performance drop isn't significant (at that FPS, it's all kind of irrelevant anyways). Since the max power draw is higher on the 2nd edition, it's probably attributed to a combination of silicon quality and throttling.dylan522p - Saturday, June 14, 2014 - link
Why did you use a 840 Evo. It is inferior to the MX100 which is also cheaper. For the same price you can get a drive with better nand and double the storage.ganeshts - Saturday, June 14, 2014 - link
Well, this piece has been in the works for a couple of months now.. When I built the refreshed config, the Samsung 840EVO was the best value for money.. I see that the MX100 came to market just a couple of weeks back..
