Doom

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 3070 Ti pairs an 8 GB GDDR6X frame buffer with a 256-bit memory bus, yielding 608.3 GB/s of bandwidth. That memory subsystem is a defining factor in Doom's performance envelope. At 1080p, the GPU's raw compute headroom—21.75 TFLOPS of FP32 throughput across 6,144 shading units—allows the game to run far beyond typical refresh-rate targets. The boost clock of 1770 MHz, built on Samsung's 8 nm process with 17,400 million transistors, keeps the Ampere architecture well-fed at lower resolutions.

The RTX 3070 Ti sits at the 74th percentile among all GPUs in the database, with an average benchmark score of 30,849. Its nearest rivals in aggregate scoring are the AMD Radeon RX 6700 (31,112, a 0.8% gap) and the NVIDIA Quadro M5000 (31,142, a 0.9% gap). Notably, the AMD Radeon RX 590 GME trails by a razor-thin 0.3% with a score of 30,755. This positioning suggests the card is competitive in synthetic workloads, but Doom's actual frame rates depend heavily on how the 8 GB VRAM interacts with texture loads at each resolution.

At 4K Ultra, the GPU's 8 GB capacity becomes a tangible constraint. The measured average of 55 FPS at 3840x2160 Ultra represents the steepest drop in the entire settings ladder, a 33.7% reduction from High's 69.3 FPS. This is not merely a shader-complexity issue; it reflects the memory pressure from Ultra textures and effects at 8.3 million pixels. The card's pixel rate of 169.9 GPixel/s and texture rate of 339.8 GTexel/s are sufficient for the geometry, but the frame buffer bandwidth and capacity dictate the ceiling. The 48 RT cores and 192 tensor cores are largely idle in this title, as Doom does not leverage ray tracing or DLSS, making raw rasterization and memory throughput the primary levers.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a classic GPU-bound scaling curve, with one critical inflection point. Moving from 1080p to 1440p at High settings, the average frame rate drops from 202.9 FPS to 132.2 FPS—a 34.8% reduction. Scaling further to 4K High yields 69.3 FPS, another 47.6% decline. This pattern indicates that the RTX 3070 Ti is the dominant bottleneck at every resolution tested; the Intel Core i7-14700F is not holding the system back.

The Low settings ladder clarifies the picture. At 1080p Low, the system hits 273.9 FPS, while 1440p Low produces 177.2 FPS and 4K Low falls to 92.8 FPS. The 1080p-to-1440p drop of 35.3% closely mirrors the High-settings drop, confirming that pixel count—not effects complexity—is the primary scaling variable. However, the 4K Low result (92.8 FPS) is telling: even with minimal graphical load, the GPU cannot break past the 100 FPS barrier, underscoring that 4K resolution alone saturates the card's capabilities.

The Ultra settings provide the most dramatic evidence of memory-induced scaling. At 1080p Ultra, the card manages 166.7 FPS—a 38.9% drop from Low's 273.9 FPS. At 1440p Ultra, the average is 108 FPS, and at 4K Ultra, it plummets to 55 FPS. The gap between High and Ultra widens as resolution increases: 8.1% at 1080p (202.9 vs 166.7), 18.3% at 1440p (132.2 vs 108), and 20.6% at 4K (69.3 vs 55). This widening delta is the signature of VRAM capacity and bandwidth strain, not just shader work. The 8 GB buffer is adequate for 1080p Ultra but increasingly marginal at 1440p and severely limiting at 4K Ultra.

Q: Does the GPU's VRAM capacity affect 1080p performance?

A: At 1080p, the 8 GB buffer is sufficient. The spread from Low (273.9 FPS) to Ultra (166.7 FPS) is a 39.1% penalty, but the card still delivers playable frame rates at every setting. The constraint becomes pronounced only at 1440p and 4K Ultra.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

1920x1080: The full settings sweep shows a clear hierarchy. Low settings deliver 273.9 FPS average, Medium drops to 234.8 FPS, High yields 202.9 FPS, and Ultra bottoms out at 166.7 FPS. The step from Low to Medium is a 14.3% reduction, Medium to High is 13.6%, and High to Ultra is 17.8%. This is a well-behaved scaling curve with no anomalies, indicating that the GPU's compute capacity—not memory—is the governing factor at this resolution.

2560x1440: The 1440p results compress the range. Low averages 177.2 FPS, Medium 153.3 FPS, High 132.2 FPS, and Ultra 108 FPS. The percentage deltas are larger than at 1080p: Low to Medium is 13.5%, Medium to High is 13.8%, and High to Ultra is 18.3%. The Ultra penalty growing from 17.8% at 1080p to 18.3% at 1440p signals the onset of memory pressure, though the card still clears 100 FPS at every setting.

3840x2160: At 4K, the curve steepens dramatically. Low averages 92.8 FPS, Medium 81.9 FPS, High 69.3 FPS, and Ultra 55 FPS. The Low-to-Medium step is 11.7%, Medium-to-High is 15.4%, and High-to-Ultra is 20.6%. The escalating deltas—particularly the 20.6% Ultra penalty—are the clearest evidence of the 8 GB VRAM ceiling. Notably, the 4K Low result (92.8 FPS) is lower than the 1440p Ultra result (108 FPS), demonstrating that raw pixel count imposes a hard floor on performance regardless of settings.

Across all resolutions, the data shows a consistent pattern: the RTX 3070 Ti is the limiting component, and the margin between settings widens as resolution increases. The combination ranks 659th out of 1,681 tested configurations for this game, placing it in the upper-middle tier of the database.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i7-14700F brings 20 cores and 28 threads to the platform, running at a base clock of 2.10 GHz and boosting to 5.40 GHz. This Raptor Lake-R part, built on Intel's 10 nm process with a 257 mm² die, is a 14th-generation desktop processor with a 65 W TDP. Its cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3, providing ample on-die storage for game logic and draw calls.

In synthetic benchmarks, the i7-14700F demonstrates strong multi-threaded capability. It scores 35,443 in Cinebench R23 multi-core and 5,003 in single-core, with a Geekbench multi-core score of 16,571 and single-core of 2,711. The PassMark multi-thread score of 41,765 further confirms its throughput. The CPU's 94th percentile ranking among all processors, with an average benchmark score of 54,097, places it in elite company. Its nearest rivals include the AMD Ryzen 9 9900X (54,450, a 0.6% lead for the AMD part) and the AMD Ryzen 9 9900X3D (54,681, a 1.1% lead), while it edges out the Intel Xeon Phi 7290 by 1.2% (53,469).

For Doom specifically, the CPU's role is to feed the GPU without becoming a bottleneck. The measured frame rates show no sign of CPU limitation: at 1080p Low, the system reaches 273.9 FPS, which is well within the CPU's capability to generate frames. The 5.40 GHz boost clock provides excellent single-thread performance for game logic, while the 20 cores handle background tasks without contention. The data indicates that even at the lowest settings and highest frame rates, the i7-14700F maintains a comfortable margin over the GPU's output.

The CPU's memory support for DDR4 and DDR5, coupled with dual-channel architecture, ensures adequate bandwidth for the GPU's 608.3 GB/s memory subsystem. The PCIe Gen 5 interface with 16 lanes (CPU only) provides a high-bandwidth connection, though Doom's data demands do not approach this limit. In this configuration, the i7-14700F is a complementary partner to the RTX 3070 Ti, never appearing as the constraining component in the measured results.
