Head-to-Head Benchmarks

The benchmark database pits the Intel Core i7-12800HX against the AMD Ryzen 7 8700G across twenty-one recorded tests. The results split decisively along workload lines, with the Intel part claiming eight wins and the AMD part taking thirteen. The largest single margin belongs to Intel in Cinebench R23 multicore, where the i7-12800HX scores 22456 against 17128 for the Ryzen 7 8700G, a 31.1% advantage. Cinebench R15 multicore reinforces that pattern, with Intel ahead 3383 to 2693, a 25.6% edge. PassMark floating point math also favors Intel heavily, 82122 versus 63815, a 28.7% gap. These are not marginal differences; they represent a substantial lead in heavily threaded sustained compute.

The Ryzen 7 8700G counters with its own decisive victories. In PassMark extended instructions, AMD leads 29067 to 23760, an 18.3% margin. That is the largest AMD win in the dataset. The 3DMark 4-thread test shows AMD ahead 3825 to 3636, a 4.9% edge, and the 8-thread test follows with 6589 versus 6292, a 4.5% lead. Single-thread performance consistently favors AMD. Cinebench R15 single-core shows a 9.1% gap, with AMD at 286 against Intel's 260. PassMark single-thread repeats this, AMD at 3928 versus 3711, a 5.5% difference. The 3DMark single-thread test is closer, AMD 1010 against Intel 999, a 1.1% margin.

Some tests land very close. PassMark data compression is nearly a tie, Intel 387535 versus AMD 386811, a 0.2% edge for Intel. PassMark multithread also sits within a hair, AMD 31690 against Intel 31585, a 0.3% difference. Cinebench R23 single-core is similarly tight, AMD 1817 versus Intel 1812, a 0.3% gap. The 3DMark 16-thread test favors AMD slightly, 7918 to 7889, a 0.4% margin. PassMark find prime numbers gives Intel a narrow win, 108 to 103, a 4.9% edge. PassMark physics goes Intel's way, 1743 to 1647, a 5.8% difference.

The most interesting split appears in 3DMark max threads. Intel scores 9119, AMD scores 7917, giving Intel a 15.2% win. Yet in the 16-thread version of the same benchmark, AMD wins by 0.4%. This suggests the Intel part scales better when thread counts exceed 16, consistent with its 24-thread configuration. AMD's wins in the 2-thread and 4-thread tests, with margins of 1.8% and 4.9% respectively, indicate stronger efficiency at lower thread counts.

The overall average benchmark scores reflect the split. Intel's average is 33875, AMD's is 33089. Intel sits at the 84th percentile of all CPUs, AMD at the 83rd. Intel's nearest rivals include the Intel Xeon 6353P at 33844, a 0.1% difference, and the Intel Core Ultra 5 338H at 33989, a 0.3% gap. AMD's nearest rivals include the Intel Core i7-13650HX at 33089, a perfect 0% difference, and the AMD Ryzen 7 7745HX at 33091, also 0%.

The Verdict

The data tells a clear story of workload-dependent superiority. The Intel Core i7-12800HX is the stronger choice for heavily threaded productivity tasks. Its Cinebench R23 multicore score of 22456 versus AMD's 17128 represents a 31.1% advantage, and the R15 multicore gap of 25.6% confirms this trend. Floating point math also favors Intel by 28.7%. Anyone running rendering, scientific computation, or compilation workloads should favor the Intel part based on these measurements.

The AMD Ryzen 7 8700G wins the single-thread and lightly threaded battles. Its Cinebench R15 single-core score of 286 against Intel's 260, a 9.1% margin, shows higher per-core efficiency. The PassMark single-thread result, 3928 versus 3711, reinforces this. The 3DMark 4-thread and 8-thread results also go AMD's way. The extended instructions test, where AMD leads by 18.3%, suggests better performance on specialized instruction sets.

The overall average scores are close, 33875 for Intel versus 33089 for AMD, a difference of roughly 2.4%. The percentile rankings are effectively identical, 84th versus 83rd. Neither chip dominates the other across the board. The selection hinges on the workload mix. Intel wins the heavy multithread scenarios decisively, AMD wins the lighter and more latency-sensitive scenarios. For mixed use, the AMD part offers more consistent wins across more tests, thirteen versus eight, but the Intel part wins by larger margins where it does prevail.

Architecture Differences

The two processors come from fundamentally different design philosophies. Intel's Core i7-12800HX uses the Alder Lake architecture on a 10 nm process at Intel's foundry. It packs 16 cores and 24 threads, a hybrid arrangement that pairs performance and efficiency cores. The die size is 215 mm². AMD's Ryzen 7 8700G uses Zen 4 architecture on a 4 nm process at TSMC, with 8 cores and 16 threads on a 178 mm² die. The transistor count for AMD is listed at 25,000 million. The process node difference, 10 nm versus 4 nm, explains part of the efficiency gap. AMD's smaller node allows higher clock speeds at similar or lower power draw.

Clock speeds differ notably. Intel's base clock is 2000 MHz with a boost of 4.80 GHz. AMD starts at 4200 MHz base and boosts to 5.10 GHz. The higher base clock for AMD contributes to its single-thread wins. The TDP figures also diverge, Intel at 55 watts, AMD at 65 watts. Despite the higher TDP, AMD achieves better single-thread scores, indicating stronger per-watt performance at lower thread counts.

Cache hierarchies differ in capacity and distribution. Intel provides 80 KB of L1 per core, 1.25 MB of L2 per core, and 25 MB of shared L3. AMD offers 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. Intel's larger L3 cache, 25 MB versus 16 MB, likely helps in cache-sensitive multithreaded workloads. AMD's smaller per-core L1 and L2 caches do not hinder its single-thread results, which remain competitive or superior.

Memory support marks a clear generational split. Intel supports both DDR4 and DDR5, while AMD supports DDR5 only. Both use dual-channel memory buses. AMD lists a memory bandwidth of 83.2 GB/s, while Intel's memory bandwidth is not recorded in the database. PCIe connectivity also differs, Intel offers Gen 5 with 20 lanes, AMD offers Gen 4 with 20 lanes. The integrated graphics are distinct as well, Intel pairs UHD Graphics 770, AMD includes Radeon 780M. Neither chip supports ECC memory. Both have unlocked multipliers.

The market segments and sockets reflect different deployment targets. Intel uses the BGA 1964 socket and targets mobile systems. AMD uses Socket AM5 and targets desktop systems. Release dates differ by roughly twenty months, Intel launched on 2022-05-09, AMD on 2024-01-07. The launch MSRP for Intel is $457, for AMD it is $329. The AMD part is smaller in die size, uses a more advanced process, and launches later, which accounts for its higher clock speeds and better single-thread performance.

Where Each One Wins

The Intel Core i7-12800HX wins decisively in heavy multithreaded compute. The Cinebench R23 multicore result, 22456 versus 17128, a 31.1% lead, makes it the clear pick for rendering, video encoding, and batch processing. Floating point math, where Intel leads by 28.7%, suggests an advantage in scientific and engineering workloads. The 3DMark max threads win of 15.2% indicates strong scaling beyond 16 threads, useful for heavily parallel applications. PassMark integer math also favors Intel, 109968 versus 103107, a 6.7% margin. Physics simulation goes Intel's way by 5.8%, and prime number finding by 4.9%. Data compression is effectively tied, but Intel edges it by 0.2%.

The AMD Ryzen 7 8700G wins in lightly threaded and latency-sensitive scenarios. Its single-thread advantage, ranging from 1.1% in 3DMark single-thread to 9.1% in Cinebench R15 single-core, makes it the better choice for everyday responsiveness, gaming, and applications that rely on a few fast cores. The 4-thread and 8-thread 3DMark wins, 4.9% and 4.5% respectively, show stronger performance in partially threaded workloads. Extended instructions, where AMD leads by 18.3%, suggests an edge in specialized code paths such as cryptography or media processing. Random string sorting favors AMD by 7.8%, indicating better memory access patterns for certain data operations. Data encryption also goes AMD's way by 3.8%. The PassMark multithread result is essentially tied, AMD ahead by 0.3%, so for general multithreaded tasks the difference is negligible.

The practical split is straightforward. For sustained all-core workloads, the Intel part provides a meaningful performance cushion. For mixed workloads with a strong single-thread component, the AMD part wins more often across the broader test suite. The 13-to-8 win count in AMD's favor reflects its broader consistency, while Intel's eight wins include the largest margins in the entire comparison. Users should weigh the size of the margins against the frequency of wins. The Intel wins are bigger, the AMD wins are more numerous. Neither chip is a universal recommendation, the data supports each in its respective domain.
