Intel Core i3-3250T vs Intel Core i5-3210M Comparison

The Verdict

The benchmark data is unambiguous: the Intel Core i3-3250T wins every single recorded head-to-head comparison against the Intel Core i5-3210M. Across five Cinebench tests, the desktop i3-3250T leads by margins ranging from 7.5% to 8.1%, with no test favoring the mobile i5-3210M. The i3-3250T also holds a higher average benchmark score of 775 versus 758 for the i5-3210M, and it sits at the 21st percentile among all CPUs compared to the i5-3210M's 20th percentile.

Given the data, the i3-3250T is the clear choice for any workload that prioritizes raw compute performance, particularly multi-threaded rendering tasks where its Cinebench R23 multicore score of 2252 outpaces the i5-3210M's 2095 by 7.5%. The i5-3210M, however, retains relevance in its specific mobile context: it is a 35 W part on the Intel Socket G2 (988B) platform, designed for laptops where the desktop socket 1155 of the i3-3250T is not an option. For a user building or upgrading a desktop system, the i3-3250T wins outright. For a user constrained to a laptop motherboard, the i5-3210M remains the only applicable choice, and its performance deficit is modest enough to be acceptable in everyday tasks.

Architecture Differences

Both processors share the same fundamental architecture: they are Ivy Bridge designs built on Intel's 22 nm process node, each with 2 cores and 4 threads. Cache configurations are identical as well, with 64 KB of L1 per core, 256 KB of L2 per core, and 3 MB of shared L3 cache. Neither chip supports ECC memory, and neither has an unlocked multiplier.

The critical architectural divergence lies in their market segments and physical platforms. The i3-3250T is a desktop part for Intel Socket 1155, while the i5-3210M is a mobile part for Intel Socket G2 (988B). This is reflected in their die sizes: the i3-3250T measures 94 mm², while the i5-3210M is substantially larger at 118 mm². The larger mobile die suggests additional integrated components or different layout priorities, though the core count and cache structure remain identical.

Clock behavior also differs. The i3-3250T runs at a fixed base clock of 3.00 GHz with no boost capability, a characteristic of the Core i3 tier. The i5-3210M has a lower base clock of 2.50 GHz but can boost up to 3.10 GHz, a feature exclusive to the Core i5 tier. Despite the i5's boost advantage in peak single-core potential, the recorded benchmarks show the i3-3250T maintaining a lead in every test, indicating that its higher sustained base clock more than compensates for the i5's short-term boost.

Integrated graphics differ as well. The i3-3250T ships with Intel HD 2500, while the i5-3210M includes the newer Intel HD 4000. Memory support is dual-channel DDR3 for both, but the i3-3250T lists a memory bandwidth of 25.6 GB/s, while the i5-3210M's bandwidth is not recorded. PCIe support is documented for the i3-3250T as Gen 3 with 16 lanes (CPU only), while the i5-3210M has no PCIe specification listed.

Head-to-Head Benchmarks

The most striking result is the consistency of the i3-3250T's victory. Across five Cinebench tests, the deltas are tightly clustered between 7.5% and 8.1%, indicating a uniform performance advantage rather than a workload-specific quirk.

In Cinebench R15 multicore, the i3-3250T scores 226 against the i5-3210M's 210, a 7.6% lead. This pattern repeats in Cinebench R20 multicore with scores of 945 and 879 respectively, a 7.5% delta. Cinebench R23 multicore shows 2252 versus 2095, again a 7.5% difference. The largest margin appears in Cinebench R20 single-core, where the i3-3250T scores 133 against 123, an 8.1% advantage. Cinebench R23 single-core follows with 318 versus 295, a 7.8% lead.

The i5-3210M does have one additional benchmark recorded that the i3-3250T lacks: Geekbench results showing a multicore score of 1116 and a single-core score of 587. However, since the i3-3250T has no corresponding Geekbench entry, no direct comparison can be made from the database. The absence of this test for the i3-3250T does not change the outcome of the head-to-head results, which show 5 wins for the i3-3250T and 0 for the i5-3210M.

Where Each One Wins

The i3-3250T wins in every measurable compute category. Its fixed 3.00 GHz clock delivers superior sustained throughput in both single-threaded and multi-threaded Cinebench workloads. The desktop platform also provides a documented PCIe Gen 3 interface with 16 lanes, which supports modern discrete graphics more explicitly than the i5-3210M's unspecified PCIe configuration. For users running rendering workloads, compiling code, or performing any CPU-intensive task on a desktop, the i3-3250T is the definitive pick based on the recorded data.

The i5-3210M's advantages are not found in raw performance but in platform suitability. It is a mobile processor with a 35 W TDP, making it appropriate for laptop systems where the i3-3250T's desktop socket cannot be used. It also includes the more capable Intel HD 4000 integrated graphics, which could matter in a laptop with no discrete GPU. Finally, the i5-3210M's boost clock up to 3.10 GHz offers a theoretical peak that could help in short, bursty workloads, even though the actual benchmarks show the i3-3250T winning all recorded single-core tests.

The data also places both processors in a similar competitive tier. The i3-3250T's nearest rivals include the Intel Celeron G5920 (identical average score of 775), the Intel Pentium Silver J5005 (776, 0.1% faster), the AMD Athlon X4 760K (777, 0.2% faster), and the Intel Core i7-3687U (773, 0.3% slower). The i5-3210M's nearest rivals are the Intel Core i3-5020U (757, 0.1% slower), the Intel Xeon E5450 (756, 0.2% slower), the Intel Core i5-4250U (756, 0.3% slower), and the Intel Core i3-3240 (761, 0.3% faster). These rivalries show both chips operating within a tight performance band around their respective average scores, with no rival exceeding a 0.3% delta in either direction.

In summary: for desktop builders, the i3-3250T is the superior processor with a consistent 7.5% to 8.1% performance edge. For mobile users, the i5-3210M is the only applicable option, and its performance deficit is modest, around 7% to 8% across the tested Cinebench workloads.
