AMD Radeon 740M vs AMD Radeon RX 7650 GRE Comparison

AMD Radeon 740M and AMD Radeon RX 7650 GRE occupy distinct positions in the database, separated by performance tier, power envelope, and intended deployment. The 740M is an integrated graphics processor within the Phoenix2 chip, while the RX 7650 GRE is a discrete, dual-slot add-in card from the Radeon RX 7000 series. Their benchmark scores, architectural resources, and recorded specifications define a clear hierarchy, though the data also reveals specific strengths for each part.

Where Each One Wins

The RX 7650 GRE wins the only head-to-head benchmark recorded in the database, the Geekbench OpenCL test, with a score of 83109 against the 740M’s 10172. That delta of 87.8% in favor of the discrete card is not a marginal difference; it is a dominant margin that places the two products in entirely different performance classes. The RX 7650 GRE’s average benchmark score of 42723, drawn from its two recorded tests, sits at the 83rd percentile of all GPUs in the database. The 740M’s average of 12870 places it at the 53rd percentile.

Where the 740M wins is not in raw throughput but in integration and power discipline. Its thermal design power is recorded at 45 W, a figure that allows it to function as an IGP with no power connectors and a motherboard-dependent display output set. The RX 7650 GRE, by contrast, carries a 170 W TDP, requires a single 8-pin power connector, and a suggested power supply of 450 W. The 740M’s system-shared memory architecture means bandwidth is system dependent, whereas the RX 7650 GRE has dedicated 8 GB GDDR6 on a 128-bit bus delivering 288.0 GB/s. For scenarios where a separate graphics card is not possible or desirable, the 740M’s existence as a 45 W IGP is the advantage. The data does not show the 740M winning any benchmark, but its physical and electrical footprint is a categorical win for compact, low-power systems.

The RX 7650 GRE also wins on architectural resource counts. It has 2048 shading units, 128 texture mapping units, 64 render output units, and 32 ray tracing cores. The 740M has 256 shading units, 16 TMUs, 8 ROPs, and 4 ray tracing cores. These are 8x differences in shading units and ROPs, and 8x in ray tracing cores. The pixel rate of the RX 7650 GRE is 172.5 GPixel/s versus 22.40 GPixel/s for the 740M. Texture rate is 345.0 GTexel/s versus 44.80 GTexel/s. FP32 compute is 22.08 TFLOPS versus 2.867 TFLOPS. Every throughput metric in the database favors the discrete card by a factor of roughly 7.7 to 8.0.

The Verdict

The database indicates a straightforward choice based on the recorded metrics. The RX 7650 GRE is the performance leader by a wide margin. Its Geekbench OpenCL score is 8.17 times higher than the 740M’s, and its FP32 throughput is 7.7 times higher. Its percentile rank of 83 versus 53 confirms that it sits well above the median GPU in the database, while the 740M sits just above the midpoint. The RX 7650 GRE’s nearest rivals include the NVIDIA GeForce RTX 4070 SUPER, with an average score of 43223 and a delta of 1.2%, meaning the RX 7650 GRE trails that card by a narrow margin. It also trails the Quadro M6000 24 GB by 1.2%, the RTX 5050 Mobile by 1.3%, and the Quadro M6000 by 1.3%. These are small deltas, indicating the RX 7650 GRE is competitive with high-end discrete cards from the previous generation.

The 740M’s nearest rivals are far less powerful. The AMD FirePro W5100 has an average score of 12847, a delta of 0.2% above the 740M. The Radeon Pro 455 and GeForce GTX 590 both sit at 12831 and 12830, respectively, each 0.3% above. The Radeon RX 580 is 0.4% below at 12928. These rival deltas are all under one percent, meaning the 740M is tightly clustered with older mid-range discrete GPUs despite being an integrated part. That is a notable result: the 740M, at 45 W, matches the average benchmark performance of discrete cards like the GTX 590 and RX 580, which draw significantly more power.

For a user who needs maximum compute throughput, ray tracing capability, and dedicated video memory, the RX 7650 GRE is the only choice in this comparison. Its 8 GB GDDR6 frame buffer and 288.0 GB/s bandwidth are dedicated resources, not shared with the system. For a user constrained to integrated graphics, the 740M is the relevant option, and the data confirms it performs at the level of older discrete GPUs. The verdict is not ambiguous: the discrete card wins all measured performance comparisons, while the IGP wins on integration and power requirements.

Head-to-Head Benchmarks

The single recorded head-to-head benchmark is Geekbench OpenCL. The RX 7650 GRE scores 83109, the 740M scores 10172. The delta is 87.8% in favor of the RX 7650 GRE. That is an 8.17x raw score difference. In practical terms, this benchmark exercises general-purpose compute through the OpenCL API, and the RX 7650 GRE’s 2048 shading units operating at a boost clock of 2695 MHz produce far more parallel throughput than the 740M’s 256 shading units at 2800 MHz. The 740M actually has a higher boost clock, 2800 MHz versus 2695 MHz, but its shading unit count is one-eighth that of the RX 7650 GRE. The clock advantage of 105 MHz does not compensate for a 1792 shading unit deficit.

Also recorded for the RX 7650 GRE is a 3DMark Steel Nomad DX12 score of 2336. The 740M has no corresponding 3DMark result in the database. That test, which runs a DirectX 12 workload, further illustrates the discrete card’s capability in modern graphics APIs. The RX 7650 GRE supports DirectX 12 Ultimate (12_2), as does the 740M, so API compatibility is not a differentiator. The differentiator is raw execution resources.

The average benchmark scores reflect the same hierarchy. The RX 7650 GRE’s average of 42723 is based on its two scores, 2336 in 3DMark Steel Nomad and 83109 in Geekbench OpenCL. The 740M’s average of 12870 is based on 10172 in Geekbench OpenCL and 15568 in Geekbench Vulkan. The Geekbench Vulkan score of 15568 for the 740M is its highest recorded result, yet it remains below the RX 7650 GRE’s OpenCL score by a factor of 5.34. The RX 7650 GRE’s OpenCL score alone is 5.34 times higher than the 740M’s best Vulkan result.

Architecture Differences

The two GPUs share the RDNA 3.0 architecture but are built on different process nodes and use different chips. The 740M uses the Phoenix2 chip on a 4 nm process from TSMC, with 20,900 million transistors on a 137 mm² die. The RX 7650 GRE uses the Navi 33 chip on a 6 nm process from TSMC, with 13,300 million transistors on a 204 mm² die. The 740M’s transistor density is 152.6 million transistors per square millimeter, while the RX 7650 GRE’s is 65.2 million per square millimeter. The 4 nm node allows the integrated part to pack more transistors per area, though the discrete chip has a larger physical die.

The 740M is part of the Navi III IGP (Phoenix) generation, with a predecessor of Navi II IGP and a successor of Navi III IGP. The RX 7650 GRE is in the Navi III (RX 7000) generation, with a predecessor of Navi II and a successor of Navi IV. The codename for the RX 7650 GRE is Hotpink Bonefish; the 740M has no codename listed. The 740M’s base clock is 800 MHz with a boost of 2800 MHz. The RX 7650 GRE has a base clock of 1720 MHz, a boost of 2695 MHz, and a game clock of 2350 MHz. Memory clocks also differ: the 740M uses system shared memory with no dedicated clock, while the RX 7650 GRE runs its GDDR6 at 2250 MHz, or 18 Gbps effective.

The RX 7650 GRE is a dual-slot card measuring 204 mm in length and 115 mm in height. It has display outputs of 1x HDMI 2.1a and 3x DisplayPort 2.1. The 740M is an IGP with motherboard-dependent display outputs and no slot width. Both use a PCIe 4.0 x8 bus interface. The RX 7650 GRE’s launch MSRP was 279 USD, a figure recorded in the database. The 740M has no launch MSRP recorded. The release dates differ by roughly a year: the 740M was released on 2024-01-30, and the RX 7650 GRE on 2025-02-06.

The FP16 and FP32 throughput ratios are identical for both parts at 1:1, meaning each card’s half-precision and single-precision compute rates are the same. The RX 7650 GRE delivers 22.08 TFLOPS in both FP16 and FP32, while the 740M delivers 2.867 TFLOPS in both. Neither part has tensor cores listed in the database. Both support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, so software feature parity exists at the API level. The architectural differences are therefore concentrated in execution resource counts, memory subsystem, process node, and physical form factor. The database shows no overlap in performance class: the RX 7650 GRE’s average score is 3.32 times the 740M’s average, and its percentile rank is 30 points higher.
