Architecture Differences

The Intel Core i7-2630QM is built on the Sandy Bridge architecture, manufactured on a 32 nm process node by Intel. It contains 1,160 million transistors on a 216 mm² die. The AMD Phenom II X6 1065T uses the older K10 architecture (codenamed Thuban), fabricated on a 45 nm process by GlobalFoundries, with 904 million transistors on a larger 346 mm² die. The process node difference is notable: the Intel chip uses a more advanced 32 nm process, while AMD uses a 45 nm process.

Cache layouts differ substantially between the two. The Intel Core i7-2630QM has 64 KB of L1 cache per core and 256 KB of L2 cache per core, with 6 MB of shared L3 cache. The AMD Phenom II X6 1065T has 128 KB of L1 cache per core and 512 KB of L2 cache per core, also with 6 MB of shared L3 cache. The AMD part has larger per-core L1 and L2 caches, but both share the same total L3 capacity.

Memory support is another point of divergence. The Intel chip uses dual-channel memory but has no listed memory support specification in the database. The AMD chip explicitly supports DDR2 and DDR3 memory, also in dual-channel configuration, with a memory bandwidth of 21.3 GB/s. The AMD chip also has ECC memory support, which the Intel chip lacks.

The integrated graphics situation is different as well. The Intel Core i7-2630QM includes Intel HD 3000 integrated graphics. The AMD Phenom II X6 1065T has no integrated graphics of its own; instead, it relies on chipset features on certain motherboards to provide display output.

The Intel processor uses the Intel Socket G2 (988B) and is classified as a mobile part. The AMD processor uses AMD Socket AM3 and is a desktop part. The Intel chip has 4 cores with 8 threads, while the AMD chip has 6 cores with 6 threads. The Intel chip's base clock is 2.00 GHz with a boost clock of 2.90 GHz, compared to the AMD chip's 2.90 GHz base and 3.40 GHz boost. The Intel chip has a TDP of 45 watts versus 125 watts for the AMD chip.

The Verdict

The data shows a clear but narrow victory for the Intel Core i7-2630QM across all five head-to-head benchmark tests. The Intel chip wins every single comparison, but the margins are consistent at around 4.6% to 4.8%. This means that for multi-threaded workloads like Cinebench rendering, the Intel chip with its 8 threads outperforms the AMD chip's 6 physical cores despite the AMD part having higher clock speeds.

For a mobile user, the Intel Core i7-2630QM offers the better combination of performance and power efficiency. Its 45 watt TDP is dramatically lower than the AMD chip's 125 watts, making it suitable for laptops where thermal and power constraints are critical. The fact that it still manages to outperform a desktop six-core processor confirms the efficiency of the Sandy Bridge architecture.

For a desktop user who already owns an AM3 motherboard and values the ability to use ECC memory, the AMD Phenom II X6 1065T could still be a reasonable choice. It also has the advantage of supporting DDR3 memory with a listed bandwidth of 21.3 GB/s. However, the benchmark results indicate that the Intel chip is faster across the board, so any performance-focused user should prefer the Intel part.

The percentile ranking reinforces this picture: both processors sit at the 27th percentile of all CPUs, meaning they are statistically equivalent in overall standing. But when directly compared, the Intel chip's higher thread count and more modern architecture give it a consistent edge. The AMD chip is not without merit, but the data does not favor it in any benchmark.

Specification Differences

The two processors differ in nearly every major specification category. The Intel Core i7-2630QM has 4 cores and 8 threads, while the AMD Phenom II X6 1065T has 6 cores and 6 threads. The base clock of the Intel chip is 2.00 GHz compared to 2.90 GHz on the AMD chip. The boost clock is 2.90 GHz on Intel versus 3.40 GHz on AMD.

TDP is one of the most striking differences: the Intel chip draws 45 watts, while the AMD chip draws 125 watts. The Intel chip uses the Intel Socket G2 (988B), while the AMD chip uses AMD Socket AM3. The process node is 32 nm for Intel and 45 nm for AMD. The Intel chip contains 1,160 million transistors on a 216 mm² die, while the AMD chip has 904 million transistors on a 346 mm² die.

Cache configurations differ per core. The Intel chip has 64 KB of L1 and 256 KB of L2 per core, while the AMD chip has 128 KB of L1 and 512 KB of L2 per core. Both have 6 MB of shared L3 cache. The Intel chip has no listed memory support, while the AMD chip supports DDR2 and DDR3. The AMD chip has a memory bandwidth of 21.3 GB/s, while the Intel chip has no listed bandwidth. ECC memory is supported only on the AMD chip. The Intel chip has integrated Intel HD 3000 graphics, while the AMD chip relies on chipset features. The Intel chip is a mobile part, and the AMD chip is a desktop part. The Intel chip was released in January 2011, while the AMD chip was released in December 2010.

Head-to-Head Benchmarks

The head-to-head comparison includes five Cinebench tests, and the Intel Core i7-2630QM wins all of them. The smallest margin is in Cinebench R20 multicore, where the Intel chip scores 1268 against the AMD chip's 1212, a 4.6% advantage. The largest margin is in Cinebench R15 multicore, where the Intel chip scores 304 versus 290, a 4.8% lead.

In Cinebench R23 multicore, the Intel chip scores 3020 compared to the AMD chip's 2888, a 4.6% difference. In single-core tests, the Intel chip also leads. Cinebench R20 singlecore shows the Intel chip at 178 versus 170 for AMD, a 4.7% advantage. Cinebench R23 singlecore shows 426 versus 407, also a 4.7% lead for Intel.

These results are consistent across both multi-core and single-core workloads. The Intel chip's advantage is not confined to heavily threaded tasks; it also wins in single-threaded performance despite the AMD chip's higher clock speeds. This suggests that the Sandy Bridge architecture's instruction efficiency compensates for the clock speed disadvantage.

The average benchmark scores reinforce these findings. The Intel Core i7-2630QM averages 1005 across all benchmarks, while the AMD Phenom II X6 1065T averages 993. The nearest rival to the Intel chip is the Intel Core i7-5600U with an identical average score of 1005, while the nearest rival to the AMD chip is the Intel Core i7-965 with a matching 993 average. The AMD chip's closest rivals are all Intel parts, which shows that it competes with older high-end desktop processors.

Where Each One Wins

The Intel Core i7-2630QM wins in every measured benchmark category. It achieves a 4.8% lead in Cinebench R15 multicore, a 4.6% lead in Cinebench R20 multicore, a 4.7% lead in Cinebench R20 singlecore, a 4.6% lead in Cinebench R23 multicore, and a 4.7% lead in Cinebench R23 singlecore. This gives it 5 wins out of 5 head-to-head comparisons.

The Intel chip's advantages are particularly relevant for mobile workloads. With a 45 watt TDP, it can deliver this level of performance in a laptop form factor, which is where its true value lies. The 8 threads from 4 Hyper-Threaded cores handle multi-threaded tasks well, as shown by the Cinebench R23 multicore score of 3020.

The AMD Phenom II X6 1065T does not win any head-to-head benchmarks, but it has attributes that matter outside of raw Cinebench performance. Its 6 physical cores provide 6 threads, and while that is fewer than the Intel chip's 8 threads, some workloads may scale differently. The chip supports ECC memory, which is a feature not available on the Intel part. It also supports DDR2 and DDR3 memory with a listed bandwidth of 21.3 GB/s, giving it flexibility in memory choices.

The AMD chip's higher base clock of 2.90 GHz and boost clock of 3.40 GHz do not translate into benchmark wins, but they do mean the chip has higher raw clock speed potential. In legacy applications that do not use many threads, this could narrow the gap, though the data does not show it overtaking the Intel chip in any single-core test.

For a desktop user with an AM3 motherboard who needs ECC memory support and does not require the lowest power draw, the AMD chip remains a functional option. For anyone else, the Intel Core i7-2630QM is the better performer according to every recorded measurement. The Intel chip also benefits from having integrated graphics, removing the need for a separate GPU in basic display scenarios, while the AMD chip requires chipset-based graphics on specific motherboards.

The production status for both processors is end-of-life, so neither is a current product. The Intel chip's release date of January 2011 and the AMD chip's release date of December 2010 place them in the same general era. The Intel chip's 32 nm process gives it a transistor density advantage, with 1,160 million transistors on a 216 mm² die versus 904 million on a 346 mm² die for AMD, allowing more computing resources in a smaller footprint.
