The NVIDIA GeForce RTX 5080 Mobile averages 38,349, sitting 0.6% lower. The NVIDIA GeForce RTX 4070 averages 37,648, which is 1.3% behind, and the NVIDIA Tesla P4 also averages 37,628, likewise 1.3% behind. These deltas are remarkably tight, all within 1.3% of one another, suggesting that in aggregate compute workloads the RTX 4080 Mobile trades blows with a much wider range of hardware than its mobile positioning might imply.

The RTX PRO 4500 Blackwell Server has no recorded benchmark scores, no average score, and no nearest rivals. Its percentile versus all GPUs is listed at 50, which is a placeholder value given the absence of measurements. The data indicates this is a newly listed or sparsely tested product, with its performance profile yet to be populated. Consequently, any quantitative comparison between the two must rely on architectural and specification differences rather than measured results.

Architecture Differences

The two GPUs belong to different architectural generations. The RTX 4080 Mobile uses the AD104 chip built on the Ada Lovelace architecture, while the RTX PRO 4500 Blackwell Server uses the GB203 chip on the Blackwell 2.0 architecture. Both are fabricated by TSMC on a 5 nm process, but the silicon designs diverge significantly in scale.

The AD104 die measures 294 mm² and packs 35,800 million transistors, yielding a density of 121.8 million transistors per mm². The GB203 die is larger at 378 mm² and contains 45,600 million transistors, with a slightly lower density of 120.6 million per mm². The transistor density difference is minimal, but the raw transistor budget of the server chip is roughly 27% higher, which enables a substantially larger execution engine.

The RTX PRO 4500 carries 10,496 shading units, 328 texture mapping units, and 112 ROPs. It also includes 82 RT cores and 328 tensor cores. The RTX 4080 Mobile has 7,424 shading units, 232 TMUs, and 80 ROPs, with 58 RT cores and 232 tensor cores. The server GPU offers approximately 41% more shading units, 41% more TMUs, 40% more ROPs, 41% more RT cores, and 41% more tensor cores.

Clock behavior also differs. The RTX 4080 Mobile has a base clock of 1290 MHz and a boost clock of 1665 MHz. The RTX PRO 4500 starts lower at 1215 MHz base but boosts much higher to 2415 MHz, a 45% higher boost ceiling. This combination of more cores and a higher boost clock explains the server card's theoretical throughput advantages. The RTX PRO 4500 delivers 50.70 TFLOPS of FP32 and FP16 (1:1), while the RTX 4080 Mobile delivers 24.72 TFLOPS in both, exactly half the server part's compute throughput.

The memory subsystem reflects the architectural split as well. The RTX 4080 Mobile uses GDDR6 at 2250 MHz with 18 Gbps effective, while the RTX PRO 4500 uses GDDR7 at 1563 MHz with 25 Gbps effective. The server card's 256-bit bus versus the mobile card's 192-bit bus, combined with faster memory, yields 800.3 GB/s versus 432.0 GB/s bandwidth, an 85% advantage.

Specification Differences

The two GPUs differ across nearly every specification field. The RTX 4080 Mobile is a GeForce 40-series product from the GeForce 40 Mobile generation, while the RTX PRO 4500 is a server Blackwell product from the Server Blackwell (Bxx) generation. The RTX 4080 Mobile is an integrated graphics package (IGP) with no power connectors and a slot width of IGP, whereas the RTX PRO 4500 is a single-slot card with one 16-pin power connector and a suggested PSU of 450 W. The mobile part has no suggested PSU listed.

Power consumption differs as well. The RTX 4080 Mobile has a TDP of 110 W, while the RTX PRO 4500 has a TDP of 165 W. The bus interface also differs: the mobile card uses PCIe 4.0 x16, and the server card uses PCIe 5.0 x16. Display outputs are listed as "Portable Device Dependent" for the mobile GPU, while the server GPU has no outputs at all. Physical dimensions for the RTX PRO 4500 are recorded as 267 mm in length, 111 mm in height, and 40 mm in width; the RTX 4080 Mobile has no dimensions listed.

Memory size and type differ substantially. The RTX 4080 Mobile has 12 GB of GDDR6, while the RTX PRO 4500 has 32 GB of GDDR7. The release dates also differ: the RTX 4080 Mobile was released on 2023-01-02, while the RTX PRO 4500 has a release date of 2026-03-16. The RTX 4080 Mobile's predecessor is GeForce 30 Mobile and its successor is GeForce 50 Mobile. The RTX PRO 4500's predecessor is Server Hopper and its successor is Server Rubin. Both are listed as Active in production status.

Where Each One Wins

The RTX 4080 Mobile wins in the domain of measured performance, simply because it has measurements. Its average benchmark score of 38,135 and 81st percentile ranking provide concrete evidence of its standing among all GPUs. It also wins on integration: the IGP form factor with no power connectors suits portable devices, and its display outputs are device-dependent, meaning it can drive whatever panel the laptop manufacturer pairs with it. Its 110 W TDP is lower than the server card's 165 W, making it the more power-efficient choice on paper for the same architectural family. The mobile card also has a higher base clock at 1290 MHz versus 1215 MHz, which can help in lightly threaded or latency-sensitive scenarios where sustained base clocks matter.

The RTX PRO 4500 Blackwell Server wins on raw compute capability across every execution unit count. Its 50.70 TFLOPS FP32 throughput is more than double the RTX 4080 Mobile's 24.72 TFLOPS. Its 800.3 GB/s memory bandwidth is 85% higher, and its 32 GB memory capacity is nearly triple the mobile card's 12 GB. The server card's boost clock of 2415 MHz is far higher, and its pixel rate of 270.5 GPixel/s versus 133.2 GPixel/s, along with a texture rate of 792.1 GTexel/s versus 386.3 GTexel/s, indicates substantially faster rasterization and texturing throughput. The PCIe 5.0 x16 interface doubles the interconnect bandwidth of the mobile card's PCIe 4.0 x16.

The RTX PRO 4500 also wins on memory technology, using GDDR7 with 25 Gbps effective speed, while the mobile card uses GDDR6 at 18 Gbps. The server card's single-slot form factor with a 16-pin connector is designed for datacenter installation, and its lack of display outputs reflects a compute-first role.

The Verdict

The database presents a clear asymmetry. The RTX 4080 Mobile is a measured, active product with a full benchmark history, an 81st percentile ranking, and tight competition among its nearest rivals. The RTX PRO 4500 Blackwell Server is a specification sheet with no recorded performance data. Its 50th percentile and zero average score are placeholders, not results.

For anyone selecting based on evidence, the RTX 4080 Mobile offers verifiable performance. Its aggregate score of 38,135 places it within 1.3% of several very different GPUs, from the low-power MX570 to the newer RTX 5080 Mobile, indicating a balanced compute profile that scales well across diverse workloads. Its 12 GB GDDR6 memory and 432.0 GB/s bandwidth are modest by server standards, but adequate for its mobile role.

The RTX PRO 4500 Blackwell Server, by contrast, promises substantially higher throughput based on its architecture. The GB203 chip with 45,600 million transistors, 10,496 shading units, and 82 RT cores points to a GPU designed for heavy parallel workloads. The 32 GB GDDR7 memory with 800.3 GB/s bandwidth and 50.70 TFLOPS FP32 suggest a part aimed at AI inference, rendering, or scientific compute in server environments.

The data indicates two different purposes. The RTX 4080 Mobile is for portable, consumer-facing graphics with measured results. The RTX PRO 4500 is for datacenter deployment where raw compute and memory capacity take precedence, and its performance will need to be validated through future benchmark entries. Until the database records scores for the server part, the RTX 4080 Mobile remains the only one of the two with demonstrated performance, while the RTX PRO 4500 remains a high-specification, untested entry.
