AMD Ryzen 9 7940HX vs Intel Arc G3 EXTREME Comparison

The Verdict

The AMD Ryzen 9 7940HX is the clear performance leader in this comparison. The recorded data shows it wins 9 of 13 head-to-head benchmark comparisons, with particularly dominant margins in multi-threaded and compute-heavy workloads. Its average benchmark score of 69875 places it in the 94th percentile of all CPUs, while the Intel Arc G3 EXTREME sits at 36699 in the 85th percentile.

The Intel Arc G3 EXTREME, however, claims victory in single-threaded performance and physics workloads. It delivers a 3% higher Cinebench R23 single-core score and an 8.2% higher PassMark single-thread score. This makes it the better choice for workloads that depend on raw single-core responsiveness.

For anyone running video rendering, code compilation, data compression, or heavy multitasking, the data points squarely to the AMD Ryzen 9 7940HX. Its Cinebench R23 multi-core score of 29400 is more than double the Intel part's 14655. The Intel Arc G3 EXTREME should be considered only when power efficiency and single-thread speed take priority over raw throughput.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 9 7940HX uses the Zen 4 architecture on a 5 nm TSMC process, built as a 16-core, 32-thread part with a base clock of 2.40 GHz and a boost clock of 5.20 GHz. Its codename is Dragon Range, and it belongs to the 7000 series. The Intel Arc G3 EXTREME uses Intel's 3 nm process with a Panther Lake codename, offering 14 cores and 14 threads, meaning no simultaneous multithreading. Its base clock is 1.90 GHz and boost clock is 4.70 GHz.

The AMD processor packs 13,140 million transistors across a dual-chip die layout of 2x 71 mm². The Intel part's transistor count and die size are not recorded in the database. Cache configurations differ substantially. AMD provides 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3. Intel provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The larger L3 on the AMD part helps multi-threaded workloads that reuse data sets across cores.

Memory support also separates the two. AMD uses DDR5 on a dual-channel bus with 83.2 GB/s bandwidth. Intel uses LPDDR5X on a dual-channel bus with 136.5 GB/s bandwidth. The Intel part has a 64% memory bandwidth advantage in the recorded specifications, which helps explain its competitive single-thread performance. PCIe connectivity differs as well: AMD offers Gen 5 with 28 lanes from the CPU, while Intel offers Gen 5 with only 4 lanes.

The integrated graphics also differ. AMD pairs the CPU with a Radeon 610M, while Intel includes an Arc B390. The AMD part has an unlocked multiplier and part number 100-000001486. Intel's multiplier is locked, and its part number is SA4R3. Both are active mobile parts with no ECC memory support. Neither part has a recorded launch MSRP in the database.

Head-to-Head Benchmarks

The Cinebench R23 multi-core test is the single most decisive result in this comparison. AMD scores 29400 against Intel's 14655, a 100.6% advantage. That means the AMD part delivers roughly double the multi-threaded rendering throughput. The PassMark integer math test shows an even larger gap: AMD scores 202883 against Intel's 71164, a 185.1% difference. This reflects both the core count advantage and the simultaneous multithreading support on the AMD side.

Data compression also heavily favors AMD. The Ryzen 9 7940HX scores 693741 versus 307094, a 125.9% lead. Extended instruction workloads show a 112.5% advantage for AMD, with scores of 51029 versus 24017. Random string sorting follows the same pattern: 81775 versus 37331, a 119.1% lead. Data encryption favors AMD by a smaller but still substantial margin of 75.8%, with scores of 41974 versus 23881.

Floating-point math favors AMD by 39.6%, with a score of 121383 against 86929. The PassMark multithread score shows a 73.5% lead for AMD: 53204 versus 30659. Even the find prime numbers test, which often rewards architectural efficiency, goes to AMD by 10.1%, with scores of 273 versus 248.

The Intel Arc G3 EXTREME wins the single-thread tests. In Cinebench R23 single-core, Intel scores 1862 versus AMD's 1807, a 3% advantage. The PassMark single-thread test shows Intel at 4293 versus 3942, an 8.2% lead. The physics test also goes to Intel: 2515 versus 2297, an 8.7% advantage. Interestingly, the physics test is the only multi-threaded workload where Intel wins, and it does so despite having fewer threads.

Specification Differences

The core and thread counts differ: AMD has 16 cores and 32 threads, while Intel has 14 cores and 14 threads. Base clocks differ by 500 MHz in AMD's favor (2.40 GHz versus 1.90 GHz), and boost clocks differ by 500 MHz as well (5.20 GHz versus 4.70 GHz). The thermal design power differs significantly: AMD is rated at 55 W, Intel at 25 W. The Intel part draws less than half the power budget while still winning single-thread tests.

The process node differs: AMD uses TSMC's 5 nm, Intel uses its own 3 nm. The sockets are incompatible: AMD uses AMD Socket FL1, Intel uses Intel BGA 2540. Cache layouts differ per core and in total: AMD's L3 is 64 MB, Intel's shared L3 is 18 MB. Memory type differs (DDR5 versus LPDDR5X), and memory bandwidth differs (83.2 GB/s versus 136.5 GB/s). PCIe lane counts differ: 28 lanes for AMD, 4 lanes for Intel. The integrated graphics differ (Radeon 610M versus Arc B390). AMD's multiplier is unlocked, Intel's is not. The codenames differ (Dragon Range versus Panther Lake), as do the generations and part numbers. Intel's transistor count, die size, and launch MSRP are not recorded.

Where Each One Wins

The AMD Ryzen 9 7940HX wins in every category that scales with core count, thread count, and large cache capacity. The Cinebench R23 multi-core result shows a 100.6% lead, making it the obvious choice for rendering, video encoding, and 3D scene compilation. The PassMark integer math result (185.1% lead) indicates strong performance in code compilation, financial modeling, and other integer-heavy tasks. Data compression (125.9% lead) and random string sorting (119.1% lead) point to advantages in database operations, file archiving, and data processing pipelines. Extended instructions (112.5% lead) and encryption (75.8% lead) further confirm its strength in scientific computing and security-related workloads.

The Intel Arc G3 EXTREME wins in single-thread responsiveness and physics simulation. The 3% Cinebench R23 single-core lead and 8.2% PassMark single-thread lead suggest better performance in lightly threaded applications, such as older games, spreadsheet recalculation, or interactive scripting. The 8.7% physics score advantage is notable because it indicates the Intel part handles certain game physics workloads more efficiently despite its lower core count. Its 25 W TDP also makes it better suited for fanless or compact mobile designs where thermal headroom is limited.

For power-sensitive mobile devices, the Intel Arc G3 EXTREME offers a compelling trade-off: roughly half the power draw of the AMD part while still delivering competitive single-thread performance and a 64% memory bandwidth advantage. For any workload that can use more than a few threads, the AMD Ryzen 9 7940HX is the stronger part. The data shows a clear split: AMD for throughput, Intel for efficiency and single-thread latency.
