Intel Core i5-6500TE vs Intel Core i7-2600 Comparison

Where Each One Wins

The benchmark split between these two processors is unusually clean. The Intel Core i7-2600 takes six of the eight recorded head-to-head wins, all of them in the Cinebench suite. The Intel Core i5-6500TE takes the remaining two, both in Geekbench. This is not a case of one chip being simply faster across the board; it is a case of two different workloads responding to different architectural strengths.

The i7-2600 wins every Cinebench test, both multi-core and single-core. The margins are consistent, ranging from 6.0% to 6.7%. In Cinebench R15 multi-core, the i7-2600 scores 455 against 428 for the i5-6500TE, a 6.3% lead. In Cinebench R23 multi-core, the gap is 6.2% (4519 versus 4255). Even in single-core Cinebench tests, where the newer Skylake architecture might be expected to close the gap, the i7-2600 remains ahead: 638 versus 600 in R23 single-core, a 6.3% margin. This suggests that Cinebench's rendering workload benefits from the i7-2600's higher clock speeds and additional threads.

The i5-6500TE wins decisively in Geekbench. The multi-core score is 2749 against 2409 for the i7-2600, a 12.4% advantage. The single-core gap is far larger: 1062 versus 712, a 33% lead. This is a substantial margin, indicating that Geekbench's workload is far more sensitive to the architectural improvements in Skylake, particularly in single-threaded integer and floating-point tasks. The i5-6500TE's advantage here is not small; it is dominant.

The overall average benchmark scores tell a similar story. The i7-2600 averages 1370 across all recorded tests, while the i5-6500TE averages 1399. The newer chip holds a 2.1% lead in the aggregate, but the distribution of wins is what matters. For Cinebench-style rendering, the i7-2600 is the stronger part. For Geekbench-style general-purpose and single-threaded tasks, the i5-6500TE is clearly superior. The percentile rankings are nearly identical, with the i7-2600 at the 36th percentile and the i5-6500TE at the 37th percentile of all CPUs, confirming that these two sit at essentially the same performance tier overall.

Architecture Differences

The two processors come from different eras and different process nodes. The i7-2600 is Sandy Bridge, built on a 32 nm process, with a die size of 216 mm² and 1,160 million transistors. The i5-6500TE is Skylake, built on a 14 nm process, with a die size of 122 mm². The transistor count for the i5-6500TE is not recorded, but the die size reduction is significant: 216 mm² versus 122 mm². This is a 43.5% smaller die on a much finer process, which explains the power and thermal differences.

The core configurations differ in threading. Both have 4 physical cores, but the i7-2600 supports 8 threads via Hyper-Threading, while the i5-6500TE has only 4 threads. This is a critical difference for multi-threaded workloads. The i7-2600 also has more shared L3 cache: 8 MB versus 6 MB. L1 and L2 caches are identical in size per core (64 KB and 256 KB respectively), but the total cache hierarchy favors the older chip.

Clock speeds tell a more nuanced story. The i7-2600 has a base clock of 3.40 GHz and a boost clock of 3.80 GHz. The i5-6500TE has a base clock of 2.30 GHz and a boost clock of 3.30 GHz. The i7-2600 runs at significantly higher frequencies across the board, which explains its Cinebench wins. However, the i5-6500TE has a much lower TDP: 35 watts versus 95 watts. This is a 63% reduction in power draw, a major advantage for compact or thermally constrained systems.

Memory support differs as well. The i7-2600 supports only DDR3, while the i5-6500TE supports both DDR3 and DDR4. The i5-6500TE has a recorded memory bandwidth of 34.1 GB/s; the i7-2600's bandwidth is not recorded. Both use a dual-channel memory bus and PCIe Gen 3 with 16 lanes (CPU only). The integrated graphics also differ: the i7-2600 has Intel HD 2000, while the i5-6500TE has HD Graphics 530. Neither chip supports ECC memory, and neither has an unlocked multiplier.

The sockets are incompatible. The i7-2600 uses Intel Socket 1155, while the i5-6500TE uses Intel Socket 1151. This means they cannot be swapped into the same motherboard. The release dates are also far apart: January 2011 for the i7-2600, October 2015 for the i5-6500TE. Both are end-of-life products.

Head-to-Head Benchmarks

The Cinebench results are consistently in favor of the i7-2600, with margins that are tight but repeatable. In Cinebench R15 multi-core, the i7-2600 scores 455 versus 428, a 6.3% win. The single-core R15 test shows 64 versus 60, a 6.7% margin. Moving to Cinebench R20, the multi-core score is 1897 against 1787, a 6.2% lead, and the single-core result is 267 versus 252, a 6% margin. Cinebench R23 follows the same pattern: multi-core 4519 versus 4255 (6.2%), single-core 638 versus 600 (6.3%). The consistency of these margins, all within a 6% to 6.7% band, suggests that the i7-2600's clock speed advantage and extra threads provide a stable, predictable benefit in this rendering workload.

The Geekbench results are a different story entirely. In Geekbench multi-core, the i5-6500TE scores 2749 against 2409 for the i7-2600, a 12.4% advantage. This is the largest multi-core win in the entire comparison, and it is even more striking given that the i5-6500TE has only 4 threads compared to the i7-2600's 8. The single-core Geekbench result is even more lopsided: 1062 versus 712, a 33% lead for the i5-6500TE. This is a massive delta, far exceeding any other difference in the data. The Skylake architecture's improvements in instruction-level parallelism, branch prediction, and memory latency are clearly reflected here.

Interpreting these results requires understanding what each benchmark measures. Cinebench is a ray-tracing workload that scales well with thread count and raw clock speed. The i7-2600 wins here because it has both: a 3.80 GHz boost clock and 8 threads. Geekbench is a more diverse set of tasks, including encryption, compression, and image processing, which are more sensitive to architectural efficiency per clock. The i5-6500TE wins here because Skylake's execution engine is substantially more efficient than Sandy Bridge's, even at lower clock speeds.

The total wins are 6 for the i7-2600 and 2 for the i5-6500TE. But the magnitude of the i5-6500TE's wins in Geekbench, particularly the 33% single-core margin, cannot be dismissed. In the aggregate average score, the i5-6500TE leads 1399 to 1370, a 2.1% difference. The data suggests that for users whose workloads resemble Cinebench, the i7-2600 is the better choice. For users whose workloads resemble Geekbench, the i5-6500TE is clearly superior.
