Q: What are the architectural foundations of each GPU?

A: The Quadro K2000D uses the GK107 chip with Kepler architecture on a 28 nm TSMC process, featuring 1,270 million transistors on a 118 mm² die. The HD Graphics P4600 uses the Haswell GT2 chip with Generation 7.5 architecture on a 22 nm Intel process, with the die size and transistor count not recorded in the database.

Q: Which GPU has a higher memory bandwidth figure?

A: The Quadro K2000D has a dedicated 2 GB GDDR5 memory pool on a 128 bit bus, delivering 64.00 GB/s. The HD Graphics P4600 uses system shared memory, with bandwidth listed as system dependent, so no fixed figure exists for comparison.

Architecture Differences

The two GPUs diverge fundamentally in their design goals and underlying silicon. The NVIDIA Quadro K2000D is a discrete workstation card built around the GK107 chip, using the Kepler architecture. It is manufactured on a 28 nm process at TSMC, with 1,270 million transistors packed into a 118 mm² die, yielding a transistor density of 10.8 million per square millimeter. The Intel HD Graphics P4600 is an integrated graphics processor (IGP) on the Haswell GT2 chip, using Intel's Generation 7.5 architecture, built on a 22 nm process at Intel's own foundry. The database records no die size or transistor count for the Intel part, reflecting its integration into a larger processor package.

The compute resources differ sharply. The Quadro K2000D carries 384 shading units, 32 texture mapping units (TMUs), and 16 raster output pipelines (ROPs). The HD Graphics P4600 has 160 shading units, 20 TMUs, and only 2 ROPs. This disparity in ROP count is particularly significant for pixel throughput: the Quadro achieves a pixel rate of 7.632 GPixel/s, while the Intel part manages 2.400 GPixel/s, a difference of more than three times. Texture rate is closer, with the Quadro at 30.53 GTexel/s versus 24.00 GTexel/s for the Intel, a 27.2% advantage for NVIDIA.

Memory architecture is another major split. The Quadro K2000D uses a dedicated 2 GB GDDR5 buffer with a 128 bit bus, providing 64.00 GB/s of bandwidth. The HD Graphics P4600 relies entirely on system shared memory, with bus width and bandwidth both listed as system dependent. This means the Intel GPU's memory performance can vary based on the host platform, while the Quadro has a fixed, dedicated allocation. The clock behavior also differs: the Quadro's base and boost clocks are not recorded, but its memory runs at 1000 MHz (4 Gbps effective), while the Intel part has a base clock of 350 MHz and a boost clock of 1200 MHz.

Feature support shows generational differences. The Quadro K2000D supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. The HD Graphics P4600 supports DirectX 12 (11_1), OpenGL 4.3, and Vulkan 1.0. The NVIDIA part offers a newer OpenGL version and a more advanced Vulkan implementation, while the Intel part has a slightly higher DirectX feature level. Display outputs also differ: the Quadro provides 2x DVI and 1x mini-DisplayPort 1.2, while the Intel IGP's outputs are motherboard dependent.

Power characteristics are inverted. The Quadro K2000D has a TDP of 51 W and uses a single-slot design with no power connectors, requiring a suggested 250 W PSU. The HD Graphics P4600 has a TDP of 84 W, but this is an IGP with no slot width, no power connectors, and no suggested PSU, since it draws from the host processor's power budget. The bus interface also differs: the Quadro uses PCIe 2.0 x16, while the Intel part uses a ring bus connection to the CPU.

Head-to-Head Benchmarks

The recorded database contains one head-to-head benchmark test: Geekbench OpenCL. In this test, the NVIDIA Quadro K2000D scores 3919 points, while the Intel HD Graphics P4600 scores 3389 points. The delta is 15.6% in favor of the Quadro, which is the sole winner in the head-to-head comparison. This gives the Quadro a 1 win, 0 loss record against the Intel part.

Contextualizing this result, the Quadro's score of 3919 places it within a narrow band of similar GPUs. Its nearest rival, the Quadro 2000D, scores 3930, a mere 0.3% higher. The Quadro 2000 scores 3898, a 0.5% deficit to the K2000D. The GeForce GT 745M at 3953 is the only close competitor to lead the K2000D, doing so by 0.9%. This clustering suggests the K2000D is performing near the expected level for its class, with no significant outlier behavior.

The Intel HD Graphics P4600's score of 3389 is also consistent with its peer group. The GeForce GT 740 leads it by 1.2% at 3431 points, and the Quadro 2000M leads by 1.3% at 3434 points. The Intel HD Graphics 530 trails by 1.7% at 3332 points, and the GeForce GT 730M trails by 2.2% at 3316 points. The P4600 sits in the middle of this cluster, with no dramatic deviations. The 15.6% gap between the two reviewed GPUs is therefore a real performance difference, not an artifact of one part over- or under-performing relative to its peers.

The data shows that the Quadro K2000D has a clear compute advantage in OpenCL workloads. The 530-point difference between the two scores is substantial in practical terms. Given that the Quadro's nearest rivals are all within 1% of its score, while the P4600's rivals are similarly clustered, the 15.6% delta represents a genuine tier separation between a discrete workstation GPU and an integrated graphics solution.

The process node difference (28 nm vs 22 nm) is notable, but the NVIDIA part still achieves higher raw throughput despite using a larger process. The FP32 performance gap is stark: 732.7 GFLOPS for the Quadro versus 384.0 GFLOPS for the Intel part, a 90.8% advantage for NVIDIA. The ROP count difference (16 vs 2) drives the pixel rate disparity, while the shading unit difference (384 vs 160) contributes to the FP32 gap.

The Verdict

The data points clearly to the NVIDIA Quadro K2000D as the superior performer in compute tasks. Its 15.6% lead in Geekbench OpenCL, combined with higher pixel rate, texture rate, and FP32 throughput, establishes a decisive advantage. The Quadro also holds a higher percentile ranking (23rd vs 20th), consistent with its benchmark win.

The Intel HD Graphics P4600, however, is not without merit. Its 22 nm process and 84 W TDP (which includes the host CPU) indicate a different design philosophy: integration rather than discrete performance. For systems where a dedicated GPU slot is unavailable or undesirable, the P4600 provides functional graphics capability without additional hardware.

The launch MSRP of 599 USD for the Quadro K2000D reflects its workstation positioning, but the database records no price for the Intel part. The Quadro's end-of-life status and the P4600's end-of-life status both indicate these are mature products no longer in active production.

Where Each One Wins

The NVIDIA Quadro K2000D wins in every recorded benchmark category. The OpenCL score of 3919 versus 3389 is the only head-to-head test, and the Quadro takes it by 15.6%. Beyond the single benchmark, the specification data shows wins in pixel rate (7.632 GPixel/s vs 2.400 GPixel/s), texture rate (30.53 GTexel/s vs 24.00 GTexel/s), and FP32 compute (732.7 GFLOPS vs 384.0 GFLOPS). The dedicated 64.00 GB/s memory bandwidth is another clear win, as the Intel part's bandwidth is system dependent with no fixed figure.

The Intel HD Graphics P4600 wins in none of the recorded benchmark tests. Its advantages are architectural rather than performance based: a smaller 22 nm process node, a higher DirectX feature level (12 (11_1) vs 12 (11_0)), and a lower power footprint when considering the system as a whole (the IGP requires no separate card slot or power connectors). The P4600 also has a higher boost clock (1200 MHz) than the Quadro's unrecorded boost clock, but this does not translate into benchmark success.

For users choosing between these two, the decision hinges on whether a discrete GPU is feasible. The Quadro K2000D is the clear choice for any workload where OpenCL compute or fixed memory bandwidth matters. The Intel HD Graphics P4600 is the only option for systems without PCIe expansion capability, and it offers a baseline level of graphics functionality adequate for basic display tasks. The data does not support any scenario where the P4600 outperforms the Quadro in raw performance metrics.
