AMD Phenom II X6 1075T vs Intel Processor N100 Comparison

Head-to-Head Benchmarks

The recorded data shows a fascinating split between these two processors, with each claiming victory in different types of workloads. The AMD Phenom II X6 1075T and Intel Processor N100 trade blows across the Cinebench suite, and the margin of victory in each case tells a clear story about their respective strengths.

The most dramatic result comes from Cinebench R23 single-core testing. Here, the Intel Processor N100 delivers a score of 910.5, which is 53.9% ahead of the AMD Phenom II X6 1075T's 420. That is a staggering gap for a single-threaded workload, and it reflects the massive architectural leap Intel's Gracemont cores have made in per-clock efficiency. The Phenom II's K10 architecture, despite its six physical cores, simply cannot keep pace when only one core is being utilized.

However, the tables turn when all cores are engaged in Cinebench R23 multi-core testing. The AMD Phenom II X6 1075T posts a score of 2975, which is 16.2% higher than the Intel Processor N100's 2559.5. This is a notable reversal, as the older six-core chip leverages its two additional physical cores to overcome the Intel part's superior per-core throughput. The N100's four Gracemont cores, while efficient, are numerically outmatched in a fully threaded render.

The Cinebench R15 multi-core result adds another layer of complexity. Here, the Intel Processor N100 wins with a score of 401.5 against the AMD's 299, a delta of 25.5% in Intel's favor. This is curious because the R23 multi-core result favored the AMD chip. The discrepancy likely stems from how each benchmark scales with thread count and memory bandwidth, but the data clearly indicates that the N100 holds a substantial lead in this older test version.

Looking at the overall benchmark averages, the two processors are remarkably close. The AMD Phenom II X6 1075T has an average benchmark score of 1024, while the Intel Processor N100 sits at 1007. The nearest rivals in the database confirm this tight grouping: the AMD Ryzen 5 PRO 2500U matches the Phenom II exactly at 1024 with a 0% delta, and the Intel Core i7-975 is just 0.1% behind at 1023. On the Intel side, the N100's nearest competitor, the Intel Core i3-7100H, is 0.2% ahead at 1009. These figures place both chips in the 27th to 28th percentile of all CPUs in the database, underscoring that neither part is a performance king, but both are competent mid-range options.

Where Each One Wins

The benchmark data paints a clear picture of workload-specific advantages. The Intel Processor N100 is the definitive winner in single-threaded applications. Its Cinebench R23 single-core score of 910.5 versus the AMD's 420 represents a 53.9% advantage, making it the obvious choice for lightly threaded tasks like everyday desktop responsiveness, legacy software, or applications that rely on a single fast core.

The AMD Phenom II X6 1075T, by contrast, demonstrates its strength in modern multi-threaded rendering. Its Cinebench R23 multi-core score of 2975 beats the N100's 2559.5 by 16.2%. This makes the older AMD chip the better pick for video encoding, 3D rendering, or any workload that can effectively utilize all available cores. The Phenom II's six cores and 6 MB of shared L3 cache give it a raw throughput advantage that the N100 cannot overcome in heavily parallel tasks.

The Cinebench R15 multi-core result, however, complicates a simple "AMD for multi, Intel for single" narrative. The N100 wins that test by 25.5%, suggesting that the Intel part may be more consistent across different generations of Cinebench's multi-core tests. This could indicate that the N100's Gracemont architecture handles the specific instruction patterns of R15 more efficiently, or that the Phenom II's older memory controller becomes a bottleneck in certain test configurations.

For users who primarily run modern, heavily threaded applications, the database suggests the AMD Phenom II X6 1075T holds an edge. For users who value single-core speed and energy efficiency, the Intel Processor N100 is the clear winner. The N100's 6 W TDP versus the Phenom II's 125 W TDP is a stark contrast that cannot be ignored in any use-case analysis, though the benchmark scores themselves are what drive the performance conclusions.

Architecture Differences

The architectural divide between these two processors is generational and profound. The AMD Phenom II X6 1075T is built on the K10 architecture, codenamed Thuban, using a 45 nm process node from GlobalFoundries. It packs 904 million transistors into a 346 mm² die, a massive physical footprint by modern standards. The Intel Processor N100, meanwhile, uses the Gracemont architecture, also its codename, built on Intel's 10 nm process. This node advantage alone explains much of the efficiency gap between the two.

The core configurations differ significantly. The Phenom II offers six cores and six threads, with no hyper-threading support. Each core has 128 KB of L1 cache and 512 KB of dedicated L2 cache, plus a shared 6 MB L3 cache. The N100 has four cores and four threads, with 96 KB of L1 cache per core and a shared 2 MB L2 cache, alongside a shared 6 MB L3 cache. The cache hierarchy design reflects their respective eras: the Phenom II's per-core L2 allocation was typical for 2010, while the N100's shared L2 approach is a modern efficiency technique.

Memory support is another major architectural differentiator. The AMD chip supports DDR2 and DDR3 memory in a dual-channel configuration, delivering 21.3 GB/s of memory bandwidth. The Intel processor supports DDR4 and DDR5, but only in a single-channel configuration, yet still achieves 38.4 GB/s of bandwidth thanks to the newer memory standards. This is a significant advantage for the N100 in memory-sensitive workloads, despite the single-channel limitation.

The integrated graphics situation is also divergent. The Phenom II has no built-in GPU; graphics are handled by chipset features on certain motherboards. The N100 includes UHD Graphics 730, making it a much more complete package for basic display output without a discrete graphics card. PCIe support differs as well: the Phenom II is limited to Gen 2, while the N100 offers Gen 3 with 9 lanes from the CPU. The N100 also supports ECC memory, whereas the Phenom II does not, though this is a niche feature for most users.

Specification Differences

The specification sheet reveals several key differences between these two processors. The most obvious is core count: the AMD Phenom II X6 1075T has six cores and six threads, while the Intel Processor N100 has four cores and four threads. This gives the AMD part a raw multi-threading advantage, though the Intel part compensates with higher single-thread efficiency.

Clock speeds tell an interesting story. The Phenom II has a base clock of 3.00 GHz and a boost clock of 3.50 GHz. The N100 lists a base clock of 100.00 GHz, which is clearly a typographical artifact in the database, but its boost clock is listed as 3.40 GHz. The N100's actual operating frequency is far lower than the Phenom II's, yet it still manages competitive single-thread performance, highlighting the efficiency of the Gracemont design.

Thermal design power is a stark differentiator. The Phenom II draws 125 W, while the N100 consumes just 6 W. This is a 119 W difference, making the Intel part dramatically more suitable for fanless or low-power designs. The socket types also differ entirely: the Phenom II uses AMD Socket AM3, while the N100 uses Intel BGA 1264, meaning they are not interchangeable in any system.

Memory support and bandwidth are other differentiating fields. The Phenom II supports DDR2 and DDR3 in dual-channel mode with 21.3 GB/s bandwidth. The N100 supports DDR4 and DDR5 in single-channel mode with 38.4 GB/s bandwidth. Despite having half the memory channels, the N100's newer memory standards give it nearly double the bandwidth.

Other specification differences include PCIe generation (Gen 2 for AMD, Gen 3 for Intel), integrated graphics (none for AMD, UHD Graphics 730 for Intel), ECC memory support (yes for AMD, no for Intel), and market segment (Desktop for AMD, Mobile for Intel). The production status also differs: the Phenom II is end-of-life, while the N100 is active. The release dates are over a decade apart, with the Phenom II launching in September 2010 and the N100 in January 2023. The N100 has a launch MSRP of $128; the Phenom II's launch price is not recorded in the database.
