Two boxes, one table

PC Build Comparison

Put two full builds next to each other. This PC build comparison lets you compare two PC builds, each with its own CPU, GPU, RAM, storage, and resolution. Winner cells mark the scored rows.

Side by side

By Mubashar Iqbal

How to compare two builds

  1. Fill Build A and Build B, or tap a preset (last-gen 1080p, budget 1080p, current 1440p, 4K high-end).
  2. Set RAM, storage, and resolution per side. A 1080p esports box can sit next to a 4K card without faking the same pixel count.
  3. Read the purple cells. Those won the row. Bottleneck percent and watts treat lower as better.

Competitor comparison tools often compare one CPU to another CPU, or one GPU to another GPU. This page compares two complete boxes, including RAM and storage, then adds a watt ballpark so a 5090 list does not look free.

How to read a tie

A 1080p last-gen box can win raw FPS against a 4K high-end list because the pixel count is kinder. That is not a bug. If both builds are meant for the same monitor, set both resolutions to that monitor before you trust the mix FPS row.

How PC build comparison scores two full boxes

PC build comparison is a combo table, not a CPU-versus-CPU spec sheet. Each side has its own CPU, GPU, RAM, storage, and resolution. Catalog mix FPS, bottleneck percent, and a watt ballpark fill the rows. Purple cells won that row. Bottleneck percent and watts treat lower as better.

A 1080p last-gen list can beat a 4K high-end list on raw FPS because the pixel count is kinder. Set both resolutions to the same monitor before you trust the mix FPS row. Watt figures are TDP plus a typical GPU band, not a wall meter and not a PSU size. Size the unit on the PSU calculator after you pick a winner.

Official power context, not a PSU shopping list

Intel’s ATX Version 3.0 design guide is why a 4090-class card wants a PSU that can ride a 12 V transient. This comparison table only shows which list pulls more on paper. Confirm the GPU’s official TBP on the vendor page before you buy cables.

How to set PC build comparison so the table is fair

PC build comparison lets each side pick its own resolution. That is useful when one list is a 1080p esports box and the other is a 4K editor. It is not useful when you want to know which list is faster on the same monitor. Set both resolutions to the panel you own, then read mix FPS.

Purple cells are row winners, not a buy button. A list can win mix FPS and lose watts. Watts here are a TDP plus GPU band, not a PSU size. Intel’s ATX 3.0 design guide is still the document for GPU transients. Size the unit on the PSU calculator after you pick a column.

Balance of one list: bottleneck calculator. One title: FPS calculator. Write-ups: Guides.

RAM and storage rows are capacity and type, not latency and not a CrystalDiskMark run. A 2 TB Gen4 NVMe beats a 1 TB SATA SSD on the storage row even if the SATA drive is newer. If both lists use the same 32 GB dual-channel kit, that row ties and you should ignore it. The useful fight is mix FPS at one resolution, then watts, then whether one CPU is holding its GPU back. If mix FPS is close, pick the list that wins bottleneck percent at that same resolution.

PC build comparison FAQ

Not on this page. Two columns stay readable on a phone when you compare two PC builds. Screenshot a winner, then swap the loser.

Check the resolution row. 1080p vs 4K will flip the FPS story. Align both sides if you want an apples comparison.

No. It is a TDP plus typical GPU band so you can see which list pulls more. Use the PSU calculator for a unit size.

No. This is a combo compare. A stronger CPU still loses if the other side has a much faster GPU at the same resolution.
