# Intel Core Ultra 5 245KF + NVIDIA GeForce RTX 4080

This desktop pairing combines Intel's 14-core Core Ultra 5 245KF with NVIDIA's GeForce RTX 4080, a configuration that sits at the 89th percentile among all tested builds. The CPU holds the 91st percentile among all processors, while the GPU occupies the 86th percentile among all graphics cards, creating a system that is positioned for demanding workloads and high-resolution gaming. No measured FPS rows exist for this exact combination, so all frame-rate expectations are estimated from the benchmark scores rather than direct game testing.

Usage Scenarios

High-refresh gaming — The RTX 4080's PassMark G3D score of 34,457 places it well above most competing GPUs, and its 3DMark Steel Nomad DX12 result of 6,567 indicates strong raw rasterization performance. The Core Ultra 5 245KF's single-core score of 5,173 in Cinebench R23 and 4,715 in PassMark single-thread tests suggests sufficient CPU throughput for high frame-rate scenarios. At 1440p and 4K, the GPU becomes the primary driver of frame rates, and the 4080's 86th percentile ranking supports expectations of smooth gameplay at those resolutions.

Streaming — The RTX 4080 carries 304 tensor cores and 76 RT cores on the Ada Lovelace architecture, which enables hardware-accelerated encoding and decoding workflows. The CPU's PassMark data encryption score of 33,381 and extended instructions score of 37,912 indicate solid processing headroom for encoding tasks alongside game rendering. The 14-thread configuration (14 cores, 14 threads) may limit simultaneous heavy multitasking, but the GPU offloads the most demanding streaming tasks.

Video editing — The CPU's Cinebench R23 multi-core score of 36,647 and PassMark multi-thread score of 43,110 place it near the AMD Ryzen 9 9900X3D (within 0.6% in average benchmark score), which is a strong indicator of rendering capability for video timelines. The GPU's 16 GB of GDDR6X memory with 716.8 GB/s bandwidth provides ample capacity for large frame buffers and effects processing. The FP32 compute of 48.74 TFLOPS accelerates effects, color grading, and export tasks in GPU-accelerated editors.

3D rendering — The 4080's FP16 throughput of 48.74 TFLOPS (1:1 ratio with FP32) is well-suited for compute-heavy renderers that leverage half-precision math. The CPU contributes with a Cinebench R20 multi-core score of 15,391 and R15 multi-core of 3,693, which are solid for CPU-based render engines. The 24 MB shared L3 cache helps maintain data throughput in larger scenes, though the lack of ECC memory support means this is not a workstation-grade rendering rig.

Software development — The Core Ultra 5 245KF's PassMark integer math score of 98,854 and floating-point math score of 131,546 indicate robust performance for compilation tasks and numerical computing. The single-thread score of 4,715 ensures responsive IDE and editor performance, while the 14 cores handle parallel builds efficiently. The DDR5 dual-channel memory bus delivers 102.4 GB/s bandwidth, which is adequate for most development workloads but not exceptional.

Student and office work — This configuration is substantially overkill for typical productivity tasks, but the data supports that it handles them with ease. The PassMark single-thread score of 4,715 ensures snappy application responsiveness, and the 91st CPU percentile means spreadsheet, document, and web workloads will never stress the components. The GPU's 1239 PassMark G2D score indicates solid 2D rendering for display output, though the lack of integrated graphics on the CPU means the discrete GPU must always be active.

Benchmark Performance

The Core Ultra 5 245KF achieves an average benchmark score of 55,093, placing it at the 91st percentile of all CPUs. This puts it within 0.6% of the AMD Ryzen 9 9900X3D (54,762 average score) and 1.9% ahead of the Intel Core Ultra 5 245K (54,053 average score). The CPU trails the Intel Core 7 253PQE by 1.5% and the Intel Core i9-14900HX by 1.6% in average score, showing it sits in a tightly contested performance band.

In multi-threaded workloads, the Cinebench R23 score of 36,647 and R20 score of 15,391 demonstrate strong parallel throughput. The PassMark multi-thread score of 43,110 and physics score of 2,998 support this picture, indicating the 14 physical cores are well-utilized in heavily threaded tasks. The single-core Cinebench R23 score of 5,173 and R15 score of 521 confirm excellent per-thread performance.

The RTX 4080's average benchmark score is 54,247, at the 86th percentile of all GPUs. It trails the NVIDIA GeForce RTX 4080 SUPER by only 0.1% (54,209 average score) and sits 1.1% ahead of the AMD Radeon Pro W5700X (54,828 average score — note this rival scores higher, meaning the 4080 is actually behind it by that margin). The 4080 leads the AMD Radeon RX 6750 GRE 12 GB by 2.6% and the AMD Radeon 8060S by 2.7%, though both rivals post higher average scores, indicating the 4080 is at the lower end of this comparison group despite its high percentile.

The combined picture is a system at the 89th percentile of all builds, with the CPU slightly stronger relative to its peers than the GPU is relative to its own. The Geekbench Vulkan score of 263,779 and OpenCL score of 214,739 highlight strong compute throughput, while the 3DMark Steel Nomad DX12 score of 6,567 confirms modern API performance.

Gaming Performance

No measured FPS data exists for this CPU+GPU combination, so the following frame-rate expectations are estimates derived from the benchmark scores. The RTX 4080's 3DMark Steel Nomad DX12 score of 6,567 and PassMark G3D score of 34,457 indicate high rasterization throughput, while the CPU's single-thread performance (Cinebench R23 single-core of 5,173) suggests minimal per-frame CPU bottlenecks in most games.

At 1080p, the CPU's strong single-thread scores and the GPU's high shading throughput (9,728 shading units) should support very high frame rates in esports and less demanding titles, though the pairing is not optimized for this resolution. At 1440p, the 4080's 16 GB of GDDR6X memory and 716.8 GB/s bandwidth are well-matched to modern game asset sizes, and the 86th GPU percentile suggests frame rates that comfortably exceed 60 FPS in most titles at high settings.

At 4K, the GPU's 280.6 GPixel/s pixel rate and 48.74 TFLOPS FP32 compute become the dominant factors. The 4080's 86th percentile ranking and near-identical average score to the RTX 4080 SUPER (0.1% difference) indicate that 4K gameplay at high settings is plausible, though ray tracing at 4K will stress the 76 RT cores. The CPU's 14 cores and 14 threads (no hyperthreading) are sufficient for modern game engines, but the lack of additional threads may show in games that leverage more than 14 threads.

Overall, the estimated gaming profile is strong at 1440p and capable at 4K, with the GPU as the primary limiter in resolution-scaling scenarios.

Small business workstations — The combination of 14 CPU cores and 16 GB GPU memory handles database operations (PassMark data compression of 460,123), financial modeling, and CAD work. The 91st CPU percentile ensures headroom for growth.

Students and researchers — The compute capabilities support machine learning experimentation (304 tensor cores) and scientific computing, though the lack of ECC memory and the high power draw (320 W GPU TDP) may be considerations for some academic environments.

CPU Analysis

The Intel Core Ultra 5 245KF is a 14-core, 14-thread desktop processor from the Core Ultra Series 2, built on Arrow Lake architecture (Arrow Lake-S codename) using TSMC's 3 nm process. The die contains 17,800 million transistors on a 243 mm² area. Base clock is 4.20 GHz with a boost clock of 5.20 GHz, and the multiplier is unlocked for overclocking.

The cache hierarchy consists of 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. The CPU supports DDR5 memory on a dual-channel bus with 102.4 GB/s bandwidth, and PCIe Gen 5 with 20 lanes (CPU only). No integrated graphics are present, and ECC memory is not supported.

The average benchmark score of 55,093 places the 245KF at the 91st percentile of all CPUs. Its nearest rivals are tightly clustered: the AMD Ryzen 9 9900X3D (54,762, 0.6% lower), Intel Core 7 253PQE (55,919, 1.5% higher), Intel Core i9-14900HX (56,004, 1.6% higher), and Intel Core Ultra 5 245K (54,053, 1.9% lower). This indicates the 245KF sits in a highly competitive performance band where small percentage differences separate the top-tier processors.

In multi-threaded workloads, the Cinebench R23 score of 36,647 and R20 score of 15,391 reflect the 14 physical cores' collective output. The PassMark multi-thread score of 43,110 and physics score of 2,998 corroborate this. For single-threaded tasks, the Cinebench R23 single-core score of 5,173 and PassMark single-thread score of 4,715 indicate strong per-core efficiency, which matters for legacy applications and games that rely on a few fast threads.

The 14-thread count (no hyperthreading) is notable — modern CPUs often have 2 threads per core, but the 245KF's 14 cores and 14 threads mean the OS sees only one thread per core. This simplifies thread scheduling but may limit performance in heavily threaded scenarios that benefit from SMT.

Build Overview

This is a desktop-class build combining an Intel Core Ultra 5 245KF (Arrow Lake, 3 nm) with an NVIDIA GeForce RTX 4080 (Ada Lovelace, 5 nm). The CPU is from the Core Ultra Series 2, released on 2024-10-23, while the GPU is from the GeForce 40-series, released on 2022-09-19 and now end-of-life.

The combined percentile is 89, meaning this build outperforms 89% of all recorded configurations. The CPU contributes a 91st percentile ranking (average score 55,093), while the GPU sits at the 86th percentile (average score 54,247). The CPU's slightly higher relative standing suggests it has more headroom above its peers than the GPU does.

The pairing is logically sound: a mid-to-high-range CPU (14 cores, 5.20 GHz boost) with a high-end GPU (16 GB GDDR6X, 48.74 TFLOPS). Neither component dramatically outclasses the other, which typically results in balanced performance across a wide range of applications. The CPU's 91st percentile and GPU's 86th percentile are close enough that neither is an obvious weak point.

The build class is desktop, meaning this is a stationary system with no power or thermal constraints from a mobile form factor. The GPU's triple-slot width and 310 mm length require a roomy case, and the 700 W suggested PSU must be respected.

Balance and Bottleneck

The CPU and GPU percentiles are close (91 vs 86), but the CPU has a slight edge in relative performance. In CPU-bound workloads — such as physics simulation (PassMark physics score of 2,998), data compression (460,123), and integer math (98,854) — the 245KF drives performance. In GPU-bound workloads — such as rasterization (G3D score of 34,457) and DirectX 12 rendering (3DMark Steel Nomad of 6,567) — the 4080 takes over.

For gaming at high resolutions, the GPU is the primary bottleneck because rendering load scales with pixel count. The 4080's 86th percentile means it will limit frame rates before the CPU in most titles at 1440p and 4K. At lower resolutions or in CPU-heavy games, the 245KF's 91st percentile ensures it can feed the GPU adequately, though the 14-thread count may become a limiting factor in games that scale beyond 14 threads.

In compute workloads, the balance depends on the task. The GPU's 48.74 TFLOPS FP32 and 304 tensor cores dominate AI and parallel math, while the CPU's 36,647 Cinebench R23 multi-core score leads in tasks that are not easily parallelized on GPU hardware. The 102.4 GB/s CPU memory bandwidth is a potential bottleneck for data-intensive CPU workloads, but the GPU's 716.8 GB/s bandwidth is ample for its tasks.

Overall, the system is GPU-limited in gaming, CPU-limited in lightly threaded productivity, and co-limited in heavily threaded mixed workloads.

Upgrade Path and Platform

The CPU uses the Intel Socket 1851 platform with the Arrow Lake architecture. The socket supports DDR5 memory on a dual-channel bus, and the CPU provides PCIe Gen 5 with 20 lanes. The GPU connects via PCIe 4.0 x16, which is backward compatible with the CPU's PCIe 5.0 lanes.

The platform's memory support is DDR5 only, with no ECC option. The dual-channel bus delivers 102.4 GB/s, which is fixed by the CPU's memory controller. Upgrading memory capacity is possible, but bandwidth is capped by the platform.

The GPU's suggested PSU is 700 W, and it draws up to 320 W TDP. The CPU has a 125 W TDP. This leaves headroom in a 700 W power supply for additional drives and peripherals, but users should verify total system draw before adding more components. The GPU uses a single 16-pin power connector and occupies a triple-slot width, so case space must accommodate its 310 mm length.

A sensible next upgrade would be a higher-tier CPU on the same socket, such as a Core Ultra 9 variant (if available in the same generation), to increase multi-threaded throughput without changing the platform. For the GPU, a move to a newer generation (the 4080's successor is the GeForce 50-series) would improve ray tracing and compute performance, but the 4080's 86th percentile means it remains capable for several more years. The CPU's active production status and the GPU's end-of-life status suggest the GPU will be the first component to warrant replacement.
