Architecture Differences

The two processors come from different architectural generations despite both being Intel products. The i7-4810MQ is based on the Haswell architecture, while the i5-5675R is based on the newer Broadwell architecture. This translates directly to their process nodes: the i7-4810MQ uses a 22 nm process with a die size of 177 mm², while the i5-5675R uses a smaller 14 nm process with a slightly larger die size of 182 mm². The transistor count for the i7-4810MQ is listed at 1,400 million, while no transistor count is provided for the i5-5675R.

Cache configurations also differ significantly. Both have 64 KB of L1 cache and 256 KB of L2 cache per core, but the shared L3 cache differs: the i7-4810MQ has 6 MB of shared L3 cache, while the i5-5675R has only 4 MB. This 2 MB difference in favor of the i7-4810MQ is notable for workloads that benefit from larger cache pools.

The integrated graphics solutions are different as well. The i7-4810MQ comes with Intel HD 4600, while the i5-5675R features Iris Pro Graphics 6200. The i5-5675R's graphics solution is more advanced, which is consistent with its newer Broadwell architecture and desktop market segment.

Memory bandwidth figures show a slight edge for the i5-5675R, which lists 29.9 GB/s compared to 25.6 GB/s for the i7-4810MQ. Both support DDR3 memory over dual-channel buses. The socket types differ entirely: the i7-4810MQ uses Intel Socket G3 for mobile systems, while the i5-5675R uses Intel BGA 1364 for desktop integration.

Head-to-Head Benchmarks

The Cinebench series of tests shows a consistent pattern of victory for the i7-4810MQ. In Cinebench R15 multi-core, the i7-4810MQ scores 516 against the i5-5675R's 476, a 8.4% advantage. The single-core R15 test shows a similar story with scores of 72 versus 67, a 7.5% edge. Moving to Cinebench R20, the multi-core gap remains at 8.4% with scores of 2154 and 1987, while the single-core gap widens slightly to 8.6% with scores of 304 and 280. The Cinebench R23 results continue the trend: multi-core scores of 5129 versus 4733 represent an 8.4% lead, and single-core scores of 724 versus 668 show an 8.4% advantage for the i7-4810MQ.

The Geekbench tests flip the script entirely. In Geekbench multi-core, the i5-5675R scores 3738, which is 14.3% higher than the i7-4810MQ's 3203. The single-core Geekbench test shows the i5-5675R scoring 1234 against 1106 for the i7-4810MQ, a 10.4% difference. This divergence between Cinebench and Geekbench results is striking, suggesting that the two processors excel under different testing methodologies. The i7-4810MQ's 8 threads give it a clear advantage in the Cinebench rendering workloads, while the i5-5675R's newer architecture and higher base clock of 3.10 GHz appear to benefit Geekbench's more varied test patterns.

The overall benchmark averages confirm how close these two processors are. The i7-4810MQ has an average benchmark score of 1651, while the i5-5675R sits at 1648, a difference of only 0.2%. This places them as direct competitors in the nearest rivals list for each other, with the i7-4810MQ showing a 0.2% delta over the i5-5675R in that comparison.

The Verdict

The data presents a nuanced picture. The i7-4810MQ is the clear winner in Cinebench workloads across all versions (R15, R20, R23), both single-core and multi-core, with consistent margins between 7.5% and 8.6%. This makes it the better choice for rendering tasks that resemble Cinebench's workload. Its 8 threads versus 4 threads provide a structural advantage that the benchmarks consistently reflect.

However, the i5-5675R wins decisively in Geekbench tests, with a 14.3% multi-core advantage and a 10.4% single-core advantage. This suggests it handles a broader range of computational tasks more efficiently, likely due to its newer Broadwell architecture and higher base clock of 3.10 GHz compared to 2.80 GHz for the i7-4810MQ. The i5-5675R also has higher memory bandwidth at 29.9 GB/s versus 25.6 GB/s.

The i7-4810MQ is the better choice for users prioritizing Cinebench-style rendering performance, given its 6 wins out of 8 benchmarks. The i5-5675R is the better choice for users who value the Geekbench performance profile, which may indicate better general-purpose responsiveness. The i5-5675R also has the advantage of being currently marked as "Active" production status, while the i7-4810MQ is listed as "End-of-life."

Specification Differences

The two processors differ in several key specifications. The i7-4810MQ has 8 threads while the i5-5675R has 4 threads, despite both having 4 cores. The base clock differs: 2.80 GHz for the i7-4810MQ versus 3.10 GHz for the i5-5675R. Boost clocks are 3.80 GHz for the i7-4810MQ and 3.60 GHz for the i5-5675R. The TDP is 47 watts for the i7-4810MQ and 65 watts for the i5-5675R, reflecting the mobile versus desktop market segmentation.

The socket types are different: Intel Socket G3 for the i7-4810MQ and Intel BGA 1364 for the i5-5675R. Process nodes differ at 22 nm versus 14 nm, and die sizes are 177 mm² versus 182 mm². L3 cache is 6 MB for the i7-4810MQ and 4 MB for the i5-5675R. Memory bandwidth is 25.6 GB/s versus 29.9 GB/s. Integrated graphics are Intel HD 4600 versus Iris Pro Graphics 6200. Market segments are Mobile versus Desktop. Production status is End-of-life versus Active. Release dates are January 2014 for the i7-4810MQ and May 2015 for the i5-5675R. Part numbers are SR1PV for the i7-4810MQ and SR2AJ for the i5-5675R.

Where Each One Wins

The i7-4810MQ wins in all Cinebench tests, which are designed to stress multi-threaded rendering and single-threaded rendering alike. Its 8 threads provide a clear 8.4% advantage in multi-core tests and a 7.5% to 8.6% advantage in single-core tests across the R15, R20, and R23 versions. This makes it the preferred processor for applications that parallelize well across threads, such as 3D rendering, video encoding, and other compute-heavy tasks that follow the Cinebench model.

The i5-5675R wins in both Geekbench tests, with a substantial 14.3% multi-core advantage and a 10.4% single-core advantage. Geekbench tests a wider variety of workloads, including memory operations, encryption, and image processing. The i5-5675R's higher base clock and newer architecture likely contribute to this success. Its higher memory bandwidth of 29.9 GB/s may also play a role in the Geekbench multi-core test.

The i5-5675R also wins on power characteristics in terms of efficiency, with the newer 14 nm process allowing a higher 65 watt TDP to deliver more raw capability per clock. The i7-4810MQ's lower 47 watt TDP is appropriate for mobile use, where power draw is more constrained. For users who need a processor in an active production status, the i5-5675R is the only option, as the i7-4810MQ is end-of-life.
