Intel Core i5-3210M vs Intel Core i7-3537U Comparison

FAQ

Q: Which processor has the higher base clock speed?

A: The Intel Core i5-3210M has a base clock of 2.50 GHz, while the Intel Core i7-3537U operates at 2.00 GHz. The i5 starts at a higher frequency, but the i7 has a slightly higher boost clock at 3.20 GHz versus 3.10 GHz for the i5.

Q: How do the two chips compare in thermal design power?

A: The Intel Core i7-3537U is rated at 17 W TDP, while the Intel Core i5-3210M is rated at 35 W TDP. The i7 is the more power-efficient part, consuming less than half the thermal budget of the i5.

Q: Do both processors use the same integrated graphics?

A: Yes, both the Intel Core i7-3537U and the Intel Core i5-3210M integrate the Intel HD 4000 graphics solution. There is no difference in the integrated GPU between the two.

Q: Which CPU wins in Cinebench R23 multi-core?

A: The Intel Core i5-3210M takes the win in Cinebench R23 multi-core with a score of 2095, compared to 1998 for the Intel Core i7-3537U. That is a 4.6% advantage for the i5.

Q: Which CPU wins in Geekbench multi-core?

A: The Intel Core i7-3537U wins Geekbench multi-core with a score of 1269, versus 1116 for the Intel Core i5-3210M. The i7 leads by 13.7% in this test.

Q: Are both processors built on the same manufacturing process?

A: Yes, both are fabricated on Intel's 22 nm process node and share the same Ivy Bridge architecture and codename. Both have a die size of 118 mm².

Architecture Differences

The two processors share a great deal of architectural DNA. Both are built on the Ivy Bridge architecture with the same 22 nm process node and the same 118 mm² die size. Both feature two physical cores with four threads via Hyper-Threading, and both integrate the Intel HD 4000 graphics. Neither supports ECC memory, and neither has an unlocked multiplier.

The meaningful differences lie in cache allocation and power envelope. The Intel Core i7-3537U carries 4 MB of shared L3 cache, while the Intel Core i5-3210M has 3 MB of shared L3 cache. That extra 1 MB on the i7 is a notable architectural advantage for workloads that benefit from larger on-chip caching. Both chips have identical per-core L1 (64 KB per core) and L2 (256 KB per core) configurations.

The socket situation separates the two as well. The i7-3537U uses Intel BGA 1023, a soldered mobile package, while the i5-3210M uses Intel Socket G2 (988B), which is a socketed mobile package. This reflects their different design intents: the i7 is a low-power ultraportable part, while the i5 is a mainstream mobile processor with a higher thermal ceiling.

The TDP difference is stark: 17 W for the i7 versus 35 W for the i5. That 18 W gap explains much of the benchmark behavior. The i5 has more thermal headroom to sustain higher clocks, while the i7 is engineered to fit into thinner, lighter systems with smaller cooling solutions. Both support dual-channel DDR3 memory, and both have the same 22 nm transistor process from Intel.

The release dates differ by roughly seven months, with the i5-3210M appearing in mid-2012 and the i7-3537U arriving in early 2013. The part numbers are SR0XG for the i7 and SR0MZ for the i5.

Head-to-Head Benchmarks

The head-to-head data reveals a split personality. In every Cinebench test, the Intel Core i5-3210M comes out ahead. In every Geekbench test, the Intel Core i7-3537U takes the lead. This is not a simple "one chip is faster" story; it is a tale of two different benchmark methodologies rewarding different design priorities.

Starting with Cinebench R15 multi-core, the i5-3210M scores 210 against 201 for the i7-3537U, a 4.3% margin. Cinebench R20 multi-core shows a similar pattern: 879 versus 839, a 4.6% edge for the i5. The single-core Cinebench R20 result is close as well, with the i5 at 123 and the i7 at 118, a 4.1% difference. Cinebench R23 continues the trend: multi-core 2095 versus 1998 (4.6% for the i5), and single-core 295 versus 282 (4.4% for the i5). Across all five Cinebench iterations, the i5-3210M wins by a consistent 4.1% to 4.6% margin. The consistency is remarkable, suggesting the higher base clock of the i5 (2.50 GHz versus 2.00 GHz) provides a steady advantage in these rendering workloads.

Geekbench flips the script entirely. In Geekbench multi-core, the i7-3537U scores 1269 against 1116 for the i5-3210M, a substantial 13.7% lead. Geekbench single-core shows 658 versus 587, a 12.1% advantage for the i7. These are much larger margins than the Cinebench wins, indicating that the i7's larger 4 MB L3 cache and higher 3.20 GHz boost clock deliver outsized benefits in the Geekbench workload mix. The i7 wins two of the seven head-to-head benchmarks, but it wins them by double-digit margins, while the i5's five wins are all in the 4% to 5% range.

The average benchmark scores tell a story of near-parity: the i7-3537U averages 766 across all tests, while the i5-3210M averages 758. That is only a 1% difference in the overall average. The i7 sits at the 21st percentile of all CPUs, and the i5 sits at the 20th percentile. Both chips are firmly in the same performance tier, with their nearest rivals clustering around the 756 to 773 average score range. The i7's nearest rival is the Intel Core i7-3687U at 773, just 0.9% higher, while the i5's nearest rival is the Intel Core i3-3240 at 761, only 0.3% higher.

The Verdict

The data paints a clear picture of two chips optimized for different priorities, despite their shared architecture. The Intel Core i5-3210M is the stronger raw performer in rendering workloads, winning every Cinebench test by a margin of roughly 4% to 5%. Its 35 W TDP and 2.50 GHz base clock allow it to sustain higher performance in CPU-intensive tasks. The Intel Core i7-3537U, meanwhile, wins decisively in Geekbench by 12% to 14%, likely aided by its larger 4 MB L3 cache and higher 3.20 GHz boost clock, all while consuming only 17 W.

For users prioritizing Cinebench-style rendering and sustained multi-threaded workloads, the i5-3210M is the better choice based on the recorded data. For users who need Geekbench-style responsiveness and single-thread agility, or who value the power efficiency of a 17 W part, the i7-3537U is the clear winner. The 21st versus 20th percentile ranking shows both chips occupy nearly the same overall performance tier, so the choice should come down to workload and power constraints rather than overall speed.

Specification Differences

The two processors differ in several key specification fields. The base clock is 2.00 GHz for the Intel Core i7-3537U and 2.50 GHz for the Intel Core i5-3210M. The boost clock is 3.20 GHz for the i7 and 3.10 GHz for the i5. The TDP is 17 W for the i7 and 35 W for the i5. The socket is Intel BGA 1023 for the i7 and Intel Socket G2 (988B) for the i5. The L3 cache is 4 MB (shared) for the i7 and 3 MB (shared) for the i5. The generation is Core i7 (Ivy Bridge) for the i7 and Core i5 (Ivy Bridge) for the i5. The release dates differ, with the i5 launching in May 2012 and the i7 in January 2013. The part numbers are SR0XG for the i7 and SR0MZ for the i5. The memory support field lists DDR3 for the i7, while the i5's memory support field is not recorded in the database.

Where Each One Wins

The Intel Core i5-3210M wins in all five Cinebench benchmarks: R15 multi-core (210 versus 201), R20 multi-core (879 versus 839), R20 single-core (123 versus 118), R23 multi-core (2095 versus 1998), and R23 single-core (295 versus 282). These wins range from 4.1% to 4.6%, and they suggest the i5 is the better choice for rendering workloads, video encoding, and any task that follows the Cinebench pattern of sustained CPU utilization. The i5's higher base clock of 2.50 GHz gives it a head start in these sustained workloads.

The Intel Core i7-3537U wins in both Geekbench tests: multi-core (1269 versus 1116) and single-core (658 versus 587). These are decisive wins of 13.7% and 12.1% respectively, far larger than the i5's Cinebench margins. The i7 also holds advantages in the specification sheet that likely contribute to these results: the larger 4 MB L3 cache and the higher 3.20 GHz boost clock. For everyday responsiveness, application launches, and lighter-threaded tasks that resemble Geekbench's workload profile, the i7-3537U is the stronger performer. Additionally, the i7's 17 W TDP makes it the clear winner for ultraportable laptops and fanless or near-silent designs, where the i5's 35 W TDP would demand a more substantial cooling solution.
