Which build to buy

The ADMI Gaming PC Intel Core i5-14400F RTX 5070 and the ADMI Gaming PC Ryzen 7 5700X RTX 5070 Ti are both UK-assembled prebuilts from the same builder with a 3-year collect-and-return warranty. The ADMI RTX 5070 costs £1,399 and pairs a 10-core Intel Core i5-14400F with the NVIDIA RTX 5070 carrying 12 GB of GDDR7 VRAM. The ADMI RTX 5070 Ti costs £1,674 and pairs an 8-core AMD Ryzen 7 5700X with the NVIDIA RTX 5070 Ti carrying 16 GB of GDDR7 VRAM. The £275 gap is buying 4 GB of extra VRAM, roughly 25 percent more GPU power, and an AMD CPU one Zen generation behind the Intel option.

ADMI RTX 5070 vs RTX 5070 Ti: the short answer

• 1440p 60 fps gamers should buy the ADMI RTX 5070. 12 GB of VRAM clears every current 1440p ultra workload and the Core i5-14400F is the newer of the two CPUs.
• 1440p high-refresh gamers should buy the ADMI RTX 5070 Ti. 16 GB of VRAM and roughly 25 percent more GPU horsepower lift 1440p ultra frame rates above 100 fps with DLSS 4.
• 4K gamers should skip both and step up to an RTX 4080 or RTX 5080 build. Neither carries enough VRAM for consistent 4K texture loads.
• Same warranty, same delivery, same case quality. The decision is purely on GPU tier and CPU generation, not on builder reputation.

GPU: RTX 5070 vs RTX 5070 Ti

The NVIDIA RTX 5070 carries 12 GB of GDDR7 VRAM. The NVIDIA RTX 5070 Ti carries 16 GB of GDDR7 VRAM. The RTX 5070 Ti outperforms the RTX 5070 by roughly 25 percent on the same 1440p workload and by roughly 30 percent at 4K. Both cards support DLSS 4 multi-frame generation, which uplifts frame rates by 2-4x in supported titles, and AV1 hardware encoding for live streaming.

VRAM is the deciding factor at 1440p ultra in 2026 AAA titles. 12 GB clears titles such as Cyberpunk 2077, Black Myth: Wukong, and Senua's Saga: Hellblade II at 1440p ultra with ray tracing on. 16 GB extends that headroom into texture-heavy titles such as The Last of Us Part II PC and Indiana Jones and the Great Circle, where 12 GB starts to hit the ceiling.

For 4K, the picture flips. The RTX 5070 Ti hits 60 fps at 4K high-medium with DLSS Performance, but ray-tracing ultra at 4K drops the frame rate below 50 fps in heavy titles. Neither GPU is the right pick for buyers who own a 4K monitor and want 60+ fps with ray tracing on. The RTX 4080 (16 GB) or RTX 5080 (16 GB) is the entry-floor for that bracket.

CPU: Intel Core i5-14400F vs AMD Ryzen 7 5700X

The Intel Core i5-14400F is a Raptor Lake Refresh chip with 10 cores (6 performance + 4 efficient) and 16 threads, boosting to 4.7 GHz. The AMD Ryzen 7 5700X is a Zen 3 chip with 8 cores and 16 threads, boosting to 4.6 GHz. The Core i5-14400F sits two CPU generations newer than the Ryzen 7 5700X.

For 1440p gaming, CPU bottlenecks against the RTX 5070 and RTX 5070 Ti are typically under 10 percent. The GPU is the limiting factor at that resolution. The Core i5-14400F runs roughly 8 percent faster than the Ryzen 7 5700X at 1080p competitive settings (where CPU matters more), but the gap collapses at 1440p ultra (where GPU does).

For productivity, the gap reverses. The Ryzen 7 5700X carries 8 full performance cores against the Core i5-14400F's 6 performance cores + 4 efficient cores, which slightly favours the Ryzen in sustained multi-thread workloads such as video encoding and 3D rendering. For pure-gaming buyers, the CPU gap is small enough that the GPU choice dominates the decision.

Which ADMI build should you buy?

Buy the ADMI RTX 5070 if

• You play at 1080p or 1440p 60 fps and do not need 100+ fps.
• You want the newer Intel Core i5-14400F CPU.
• You want to save £275 for peripherals or a 1440p monitor.

Buy the ADMI RTX 5070 Ti if

• You play at 1440p high-refresh and want 100+ fps in current AAA titles with DLSS 4.
• You want 16 GB of VRAM as a hedge against future texture requirements.
• You favour the Ryzen 7 5700X's 8 full performance cores.

Verdict

The ADMI Gaming PC Intel Core i5-14400F RTX 5070 is the strongest pure-value buy at £1,399. 12 GB of VRAM clears every current 1440p ultra workload, and the i5-14400F is the newer of the two CPUs. The ADMI Gaming PC Ryzen 7 5700X RTX 5070 Ti at £1,674 is the right pick for 1440p high-refresh gamers who want 16 GB of VRAM and roughly 25 percent more GPU horsepower. Both ship with the same 3-year UK warranty and Windows 11 pre-installed, so the decision is purely a GPU-tier conversation.
