# Thief Performance Analysis: Intel Core Ultra 9 290K Plus + AMD Radeon RX 9070 XT

The Intel Core Ultra 9 290K Plus paired with the AMD Radeon RX 9070 XT delivers a compelling 1080p and 1440p experience in Thief, though 4K Ultra settings push the combination to its limits. This pairing combines a 24-core, 24-thread Arrow Lake Refresh flagship with a Navi 48-based RDNA 4.0 graphics card, producing frame rates that range from a buttery-smooth 237 FPS at 1080p Low to a playable-but-tight 56 FPS at 4K Ultra. The data shows a clear progression: this system is built for high-refresh 1440p gaming, with 4K requiring settings compromises to maintain fluid motion.

Resolution Scaling

The measured FPS data reveals how Thief's engine responds to pixel count changes. At 1080p Low settings, the combination produces 237 FPS average. Moving to 1440p Low drops that to 174 FPS, a 26.6% reduction. Jumping to 4K Low yields 102 FPS, which represents another 41.4% drop from the 1440p figure. This scaling pattern indicates that at lower settings, the GPU remains the primary bottleneck even at high resolutions, but the CPU has enough headroom to feed the graphics card effectively.

With High settings, the resolution scaling story shifts. At 1080p High, the system averages 147 FPS. At 1440p High, that falls to 101 FPS—a 31.3% decrease. At 4K High, the average lands at 59 FPS, a 41.6% drop from the 1440p result. The consistency of these percentage drops across settings tiers suggests the game's rendering workload scales predictably with pixel count, and the RX 9070 XT's 16 GB GDDR6 memory buffer handles the increased texture and geometry demands without hitting capacity walls.

The Ultra setting tests tell the most revealing story about this combination's ceiling. At 1080p Ultra, the system hits 140 FPS average. At 1440p Ultra, it drops to 96 FPS—a 31.4% reduction. At 4K Ultra, the average collapses to 56 FPS, a 41.7% decline from the 1440p number. This pattern means the GPU is doing proportionally similar work at each resolution, but the absolute frame rates at 4K Ultra (56 FPS) fall below the 60 FPS threshold that many players consider the minimum for smooth gameplay. The data indicates that 4K Ultra is the boundary condition for this hardware pairing, while 1440p Ultra at 96 FPS represents the sweet spot for demanding visual quality.

GPU Role

The AMD Radeon RX 9070 XT sits at the heart of this system's graphics performance. Built on the RDNA 4.0 architecture with the Navi 48 chip, this card features 4096 shading units, 256 texture mapping units, and 128 raster operation units. The boost clock reaches 2970 MHz, with a game clock of 2400 MHz and a base clock of 1660 MHz. These clock speeds, combined with 16 GB of GDDR6 memory on a 256-bit bus, provide 644.6 GB/s of memory bandwidth—a figure that proves sufficient for Thief's 2014-era engine even at 4K resolution.

The GPU's benchmark scores contextualize its position in the broader market. The 3DMark Steel Nomad DX12 test yields a score of 7260, while PassMark's G3D test produces 26795 points. The GPU's percentile ranking sits at 55, meaning it outperforms just over half of all tested graphics cards. The nearest rivals in the database are surprisingly modest: the AMD Radeon HD 7770M (0.1% delta), NVIDIA GeForce GTX 570 (0.2% delta), and NVIDIA P106-090 (0.5% delta). This near-parity with older, lower-tier cards in synthetic benchmarks contrasts sharply with the game's measured performance, suggesting that Thief's workload favors the RX 9070 XT's modern architecture in ways that older benchmark suites don't capture.

The memory subsystem deserves attention. With 16 GB of GDDR6 RAM, the card has ample capacity for Thief's textures, even at 4K Ultra settings. The memory clock runs at 2518 MHz, translating to 20.1 Gbps effective. This bandwidth allocation explains why the frame rate drop from 1080p Ultra (140 FPS) to 4K Ultra (56 FPS) follows a consistent 41.7% reduction—the memory bandwidth scales with the resolution demand without becoming a limiting factor. The 64 ray tracing cores and 48.66 TFLOPS FP32 compute performance are more than sufficient for this game, which launched in 2014 and doesn't utilize modern ray tracing features.

CPU Role

The Intel Core Ultra 9 290K Plus provides the processing backbone for this system. With 24 cores and 24 threads, this Arrow Lake Refresh processor runs at a base clock of 3.70 GHz and boosts to 5.80 GHz. The 3 nm TSMC process node packs 17,800 million transistors into a 243 mm² die, with 36 MB of shared L3 cache. This configuration delivers strong single-thread performance, which Thief's engine relies on for game logic and physics calculations.

CPU benchmark results show the processor's capability. The Cinebench R23 multi-core test produces a score of 51731, while the single-core test yields 7303. PassMark's multi-thread test scores 60860, and the single-thread test reaches 4823. The processor's percentile ranking against all CPUs is 96, placing it in the top 4% of all tested processors. The average benchmark score of 84003 puts it in close competition with the Intel Core Ultra 9 285K (0.2% delta), AMD EPYC 4584PX (1.1% delta), and AMD EPYC 9135 (1.2% delta). The AMD EPYC 7F72 scores slightly higher at 85072, representing a -1.3% delta from the 290K Plus.

In Thief, the CPU's role becomes apparent when examining the frame rate scaling with resolution. At 1080p Low, the system produces 237 FPS, which is well above what most displays can show. The fact that frame rates remain high even at 1080p indicates the CPU isn't bottlenecking the GPU at lower resolutions. The 24-thread configuration handles the game's background tasks easily, and the 5.80 GHz boost clock ensures that single-threaded game logic runs with minimal latency. The memory bandwidth of 115.2 GB/s on the dual-channel DDR5 interface provides sufficient data throughput for the CPU to feed the GPU without stalling.
