A: The Intel Core i5-2450P has a base clock of 3.20 GHz, while the Intel Pentium 6805 has a base clock of 1100.00 MHz. However, the Pentium's boost clock reaches 3.00 GHz, which is lower than the i5-2450P's 3.50 GHz boost.

The Verdict

The data points to a clear, though narrow, victory for the Intel Pentium 6805 in raw compute performance. Across all six Cinebench tests, the Pentium consistently outperforms the i5-2450P by margins between 4.4% and 5.6%. The average benchmark score of 1099 versus 1086 reinforces this pattern, placing the Pentium in a slightly higher percentile ranking (31st versus 30th).

For users prioritizing multi-threaded workloads such as video encoding or 3D rendering, the Pentium 6805 is the stronger choice despite having only 2 physical cores. Its 4 threads, combined with the newer Ice Lake architecture and 10 nm process, deliver better Cinebench R23 multi-core scores (3801 versus 3632) than the older quad-core Sandy Bridge design.

Single-thread performance also favors the Pentium. In Cinebench R23 single-core, it scores 536 against the i5's 512, a 4.5% advantage. This translates to snappier day-to-day responsiveness in lightly threaded applications.

However, the i5-2450P is not without merit. Its 95 W TDP and desktop socket (Intel Socket 1155) indicate it is designed for stationary systems where power draw is less critical. The Pentium 6805, with its 15 W TDP and mobile BGA 1526 socket, is clearly intended for laptops and compact devices where efficiency is paramount.

The verdict is straightforward: if the task is purely about benchmark performance, the Intel Pentium 6805 wins. If the requirement is a desktop processor with a traditional socket and higher power budget, the i5-2450P remains a viable option, though its performance is measurably lower in every recorded test.

Head-to-Head Benchmarks

The head-to-head data leaves no ambiguity: the Intel Pentium 6805 wins every single comparison. The largest margin comes in Cinebench R15 single-core, where the Pentium scores 54 against the i5's 51, a 5.6% difference. This test measures raw single-threaded capability, and the newer Ice Lake core clearly has the edge.

In multi-core tests, the pattern is consistent. Cinebench R15 multi-core shows the Pentium at 383 versus 366 for the i5, a 4.4% lead. Cinebench R20 multi-core repeats the exact same percentage gap (1596 versus 1525, also 4.4%). Cinebench R23 multi-core follows suit with 3801 versus 3632, again a 4.4% difference. The consistency of these margins suggests the Pentium's architectural efficiency overcomes its core-count disadvantage.

Single-core results in the newer tests are nearly as consistent. Cinebench R20 single-core gives the Pentium 225 against 215, a 4.4% lead. Cinebench R23 single-core shows 536 versus 512, a 4.5% advantage. Only Cinebench R15 single-core deviates slightly with the 5.6% margin.

The Geekbench results are not part of the head-to-head table, but the recorded data shows the i5-2450P scoring 1796 in multi-core and 590 in single-core. These figures are not directly comparable to the Pentium's missing Geekbench scores, but they do provide context for the i5's overall standing.

What is notable is that the Pentium achieves these wins despite having a much lower base clock (1100.00 MHz versus 3.20 GHz) and a lower boost clock (3.00 GHz versus 3.50 GHz). The architectural improvements from Sandy Bridge to Ice Lake more than compensate for the clock speed deficit. The 10 nm process node and the larger 80 KB L1 cache per core (versus 64 KB) contribute to this efficiency.

Specification Differences

The two processors differ in nearly every major specification category. The Intel Core i5-2450P has 4 cores and 4 threads, while the Intel Pentium 6805 has 2 cores and 4 threads. Base clocks are starkly different: 3.20 GHz for the i5 versus 1100.00 MHz for the Pentium. Boost clocks also favor the i5 at 3.50 GHz versus 3.00 GHz.

Thermal design power is another major divergence. The i5-2450P draws 95 W, while the Pentium 6805 sips just 15 W. This makes the Pentium far more suitable for thin-and-light laptops, whereas the i5 is a desktop part.

Socket compatibility is entirely different. The i5-2450P uses Intel Socket 1155, a desktop socket. The Pentium 6805 uses Intel BGA 1526, a ball-grid array soldered directly to the motherboard, typical of mobile platforms.

Memory support differs as well. The i5-2450P supports DDR3 memory, while the Pentium 6805 supports DDR4. Both use dual-channel memory buses. The Pentium's memory bandwidth is listed at 51.2 GB/s, while the i5-2450P has no recorded memory bandwidth figure.

Process node and physical dimensions also differ. The i5-2450P is manufactured on a 32 nm process with a die size of 216 mm² and 1,160 million transistors. The Pentium 6805 uses a 10 nm process with a die size of 123 mm²; its transistor count is not recorded.

PCIe support shows a difference: the i5-2450P is listed with Gen 3, 16 lanes (CPU only), while the Pentium 6805 is listed simply as Gen 3 without a lane count. Integrated graphics are present only on the Pentium (UHD Graphics 32EU); the i5-2450P has none listed.

The release dates are separated by over eight years. The i5-2450P launched on 2012-01-29, while the Pentium 6805 launched on 2020-09-30. The Pentium's production status is marked as end-of-life, while the i5's status is not recorded. Neither processor has an unlocked multiplier.

Architecture Differences

The architectural gap between these two processors is substantial. The i5-2450P is based on Sandy Bridge, a 32 nm design from Intel's second-generation Core lineup. The Pentium 6805 uses Ice Lake, specifically the Ice Lake-Y variant, built on a 10 nm process. This represents a full two-node shrink and roughly eight years of microarchitectural evolution.

The core design philosophy differs significantly. Sandy Bridge uses a monolithic quad-core layout with a shared 6 MB L3 cache. Ice Lake-Y, as used in the Pentium 6805, is a dual-core design with a shared 4 MB L3 cache and 4 threads via hyper-threading. The cache hierarchy also differs: the i5-2450P has 64 KB of L1 cache per core, while the Pentium 6805 has 80 KB per core. Both have 256 KB of L2 per core.

The transistor count is only recorded for the i5-2450P at 1,160 million, reflecting the older 32 nm process. The Pentium's 10 nm design likely packs more transistors into a smaller area, but the database does not list a figure. The die size difference (216 mm² versus 123 mm²) indicates the Pentium is considerably smaller despite the more advanced node.

Memory architecture also differs. The i5-2450P supports DDR3, which was standard for its era. The Pentium 6805 supports DDR4, offering higher bandwidth potential. The recorded memory bandwidth of 51.2 GB/s for the Pentium highlights the advantage of newer memory technology.

The Pentium includes integrated UHD Graphics with 32 execution units, a feature entirely absent from the i5-2450P. This makes the Pentium a complete system-on-chip solution for mobile devices, while the i5 requires a separate graphics card.

The socket difference reflects their intended markets. The i5-2450P's Socket 1155 allows for user-upgradable desktop builds. The Pentium's BGA 1526 is soldered, meaning it is not user-replaceable. This is typical for ultra-portable and low-power designs.

The production status is another differentiator. The Pentium 6805 is explicitly marked as end-of-life, while the i5-2450P's status is not recorded in the database. Given its 2012 release, it is likely also discontinued, but the data does not confirm this.

In summary, the Pentium 6805 represents a complete architectural overhaul relative to the i5-2450P. Newer process node, different core design, updated memory support, integrated graphics, and a mobile-focused form factor all contribute to its superior benchmark results despite lower clock speeds and fewer physical cores.
