GIGABYTE BRIX GB-BXi7-4500 Review: Intel Core i7 in a UCFF PCby Ganesh T S on October 9, 2014 7:00 AM EST
Performance Metrics - I
The GIGABYTE GB-BXi7-4500 was evaluated using our standard test suite for low power desktops / industrial PCs. We revamped our benchmark suite earlier this year after the publication of the Intel D54250WYK NUC review. We reran some of the new benchmarks on the older PCs 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
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. These scores are heavily influenced by the CPU in the system as well as the clock speeds. The i7-4500U is clocked higher than the i5-4250U in the Intel NUCs, but it is not as powerful as, say, the i7-4770R in the BRIX Pro. This is understandable, given the wide gulf in the TDPs (15W for the i7-4500U vs. 45W for the i7-4770R and 47W for the i5-4200H).
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. As expected, the units with powerful processors and dedicated / higher-end GPUs fare better than the BXi7-4500U. However, an interesting aspect to note is that the single-threaded performance of the i7-4500U seems to be a tad better compared to the i5-4200H (which has a much higher TDP). However, multi-threaded rendering looks to be TDP-constrained, as the i5-4200H pulls ahead.
