AMD Radeon Vega 8 Mobile vs NVIDIA Quadro P5000 Comparison

Head-to-Head Benchmarks

The recorded data contains two direct head-to-head comparisons between the NVIDIA Quadro P5000 and the AMD Radeon Vega 8 Mobile, and the results split cleanly along workload type.

In Geekbench OpenCL, the NVIDIA Quadro P5000 delivers a score of 52,509 against the AMD Radeon Vega 8 Mobile's 7,435. That is a delta of 606.2% in favor of the Quadro, a massive gap that reflects the compute-oriented design of the discrete workstation card. The Quadro's raw throughput advantage here is not incremental; it is an order of magnitude larger than what the integrated Vega solution can muster. For any OpenCL compute task, the database shows the Quadro P5000 as overwhelmingly faster.

The situation flips in Geekbench Vulkan. There, the AMD Radeon Vega 8 Mobile scores 6,970, while the NVIDIA Quadro P5000 scores 6,342. The AMD part wins by 9%. This is a narrower margin than the OpenCL result, but it is still a clear victory for the Vega 8 Mobile. The Vulkan test appears to favor the newer architecture's graphics pipeline efficiency, or at least the specific driver and hardware combination of the Raven Ridge IGP. The Quadro P5000, despite its enormous compute advantage, trails in this particular API test.

The head-to-head tally is one win each. The NVIDIA Quadro P5000 takes the OpenCL benchmark, and the AMD Radeon Vega 8 Mobile takes the Vulkan benchmark. Neither part dominates the other across both recorded comparisons.

Looking at the broader benchmark averages, the Quadro P5000 holds an average score of 8,039 across all its recorded tests, while the Vega 8 Mobile averages 7,203. That puts the Quadro roughly 11.6% ahead in aggregate, though the two parts sit in adjacent percentile tiers: the Quadro at the 41st percentile of all GPUs, the Vega 8 Mobile at the 39th. The rivals around each part reinforce this positioning. The Quadro P5000's nearest rivals include the GeForce GTX 880M at 8,040 (0% delta), the GTX 650 Ti at 8,053 (-0.2%), and the GTX 650 Ti Boost at 8,067 (-0.3%). The Vega 8 Mobile's nearest rivals include the GeForce GTX 750 at 7,222 (-0.3%), the GTX 560 SE at 7,171 (0.4%), and the Intel Iris Pro Graphics P580 at 7,170 (0.5%). The Quadro sits in a cluster of older desktop discrete GPUs, while the Vega 8 Mobile sits in a cluster that mixes older discrete cards and a high-end integrated part.

Where Each One Wins

The NVIDIA Quadro P5000 is the clear choice for compute-heavy workloads. Its 606.2% OpenCL advantage over the Vega 8 Mobile is the single largest margin in the head-to-head data. The Quadro also carries a massive memory bandwidth advantage: 288.5 GB/s from 16 GB of GDDR5X on a 256-bit bus, versus the Vega 8 Mobile's system-shared memory with bandwidth listed as system dependent. The Quadro's 8.873 TFLOPS of FP32 performance dwarfs the Vega 8 Mobile's 1,127.4 GFLOPS. For any task that relies on raw shader throughput, texture work, or pixel output, the Quadro P5000 is the superior part. Its texture rate of 277.3 GTexel/s and pixel rate of 110.9 GPixel/s leave the Vega 8 Mobile's 35.23 GTexel/s and 8.808 GPixel/s far behind.

The AMD Radeon Vega 8 Mobile wins in exactly one recorded benchmark: Geekbench Vulkan. Its 9% lead over the Quadro P5000 suggests that for Vulkan-based graphics workloads, the newer GCN 5.0 architecture with its 2:1 FP16 ratio (2.255 TFLOPS versus the Quadro's 138.6 GFLOPS at 1:64) provides an efficiency edge. The Vega 8 Mobile is an IGP with a 25 W TDP, so it fits in systems where a discrete card cannot. It also has no power connectors and uses system-shared memory, making it a zero-footprint solution for portable devices. For users whose primary graphics API is Vulkan, the data shows the Vega 8 Mobile outperforming the Quadro P5000.

The practical split is straightforward: compute and traditional graphics workloads belong to the Quadro P5000; Vulkan-specific graphics and ultra-low-power integrated use cases belong to the Vega 8 Mobile.

Specification Differences

The two GPUs diverge sharply in nearly every physical and electrical specification. The NVIDIA Quadro P5000 is built on a 16 nm TSMC process with 7,200 million transistors on a 314 mm² die, while the AMD Radeon Vega 8 Mobile uses a 14 nm GlobalFoundries process with 4,940 million transistors on a 210 mm² die. Transistor density is similar: 22.9M per mm² for the Quadro, 23.5M per mm² for the Vega.

Clock speeds tell opposite stories. The Quadro P5000 runs at a 1607 MHz base and 1733 MHz boost, with memory at 1127 MHz (9 Gbps effective). The Vega 8 Mobile runs at a 300 MHz base and 1101 MHz boost, far lower clocks that reflect its integrated, power-constrained design. The Quadro's memory subsystem is a dedicated 16 GB GDDR5X pool on a 256-bit bus with 288.5 GB/s bandwidth; the Vega 8 Mobile uses system-shared memory with system-dependent bandwidth.

Compute unit counts differ by a factor of five. The Quadro P5000 has 2,560 shading units, 160 TMUs, and 64 ROPs. The Vega 8 Mobile has 512 shading units, 32 TMUs, and 8 ROPs. The Quadro's TDP is 180 W with a single 8-pin power connector and a suggested PSU of 450 W; the Vega 8 Mobile's TDP is 25 W with no power connectors. The Quadro is a dual-slot PCIe 3.0 x16 card measuring 267 mm by 111 mm; the Vega 8 Mobile is an IGP with no slot width, no dimensions, and no bus interface beyond the integrated package.

Display outputs also differ: the Quadro offers 1x DVI and 4x DisplayPort 1.4a, while the Vega 8 Mobile's outputs are listed as portable device dependent. The Quadro launched on 2016-09-30 with a launch MSRP of 2,499 USD; the Vega 8 Mobile launched on 2019-01-07 with no MSRP in the database.

Architecture Differences

The NVIDIA Quadro P5000 uses the GP104 chip with the Pascal architecture, part of the Quadro Pascal generation. It supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The AMD Radeon Vega 8 Mobile uses the Raven-M chip with the GCN 5.0 architecture, part of the Vega IGP generation (Raven Ridge-M). It supports the same DirectX 12 (12_1) and OpenGL 4.6, but only Vulkan 1.3, one version behind the Quadro's 1.4.

The FP16 capabilities reveal a fundamental architectural difference. The Quadro P5000 delivers 138.6 GFLOPS of FP16 at a 1:64 ratio, meaning its FP16 throughput is a tiny fraction of its FP32 output. The Vega 8 Mobile delivers 2.255 TFLOPS of FP16 at a 2:1 ratio, meaning its FP16 throughput is double its FP32 output. This makes the Vega architecture substantially more efficient at half-precision work, which likely contributes to its Vulkan benchmark win.

Both parts lack dedicated ray tracing cores and tensor cores. Neither GPU has any hardware acceleration for those workloads in the database.

The Vega 8 Mobile's predecessor is listed as GCN 3.0 IGP and its successor as Navi II IGP. The Quadro P5000's predecessor is Quadro Maxwell and its successor is Quadro Volta. Both are marked as end-of-life in production status.

The Verdict

The database paints a clear picture for two very different users.

For anyone running OpenCL compute workloads, the NVIDIA Quadro P5000 is the only rational choice. Its 52,509 OpenCL score is 606.2% higher than the Vega 8 Mobile's 7,435. The Quadro also delivers 288.5 GB/s of dedicated memory bandwidth, 8.873 TFLOPS of FP32 throughput, and a 110.9 GPixel/s pixel rate. Its 16 GB GDDR5X frame buffer is a workstation-class resource. The 41st percentile ranking and average score of 8,039 place it alongside older desktop discrete GPUs like the GeForce GTX 880M, but its compute capability far exceeds that cluster's typical workload.

For anyone constrained to a 25 W integrated solution, the AMD Radeon Vega 8 Mobile is the functional option. It wins the Vulkan benchmark by 9%, and its 2:1 FP16 ratio gives it a half-precision advantage that the Quadro cannot match. Its 39th percentile ranking and average score of 7,203 put it in the same performance tier as the GeForce GTX 750 and GTX 560 SE, which is remarkable for an IGP.

The Quadro P5000 costs 2,499 USD at launch and requires a 450 W PSU with a dual-slot PCIe slot. The Vega 8 Mobile costs nothing extra, consumes no additional power beyond its 25 W TDP, and fits in any portable device with a Raven Ridge-M processor. The choice is not about which GPU is "better" in absolute terms; it is about which workload matters more. OpenCL and traditional graphics belong to the Quadro. Vulkan and ultra-mobile integration belong to the Vega. The head-to-head record is 1-1, and the correct pick depends entirely on the application.
