Core i7-8700 vs Dell XPS 8940 Motherboard
Shopping for cpus, motherboards & memory can get confusing when a processor and a motherboard appear side by side. The practical question is not which component is universally better: it is whether your build or repair needs a standalone CPU or the main board for a specified Dell desktop. The Intel Core i7-8700 and Dell XPS 8940 Desktop Motherboard address those very different jobs.
Quick verdict
Choose the Intel Core i7-8700 when the need is a replacement desktop processor with the listed LGA 1151 socket designation. Choose the Dell XPS 8940 Desktop Motherboard when the job is centered on a Dell XPS 8940 board and its stated 10th- and 11th-generation Intel processor scope. Their listed prices are separated by $97.58, but that gap reflects two different component roles rather than two versions of the same upgrade.
At-a-glance comparison
| Detail | Intel Core i7-8700 | Dell XPS 8940 Desktop Motherboard |
|---|---|---|
| Listed price | USD 64.00 | USD 161.58 |
| Condition | Used | New |
| Component role | Desktop CPU | Desktop motherboard |
| Listed processor detail | Core i7 8th Gen, 6 cores | 10th- and 11th-gen Intel Core processors |
Where each component wins
Intel Core i7-8700 wins for a CPU-only need. Its six-core Core i7 designation, 3.20 GHz clock speed, and 12 MB L3 cache describe a complete desktop processor rather than a board. It is the relevant direction when an existing setup calls for an LGA 1151 processor and the motherboard is already in place.
Dell XPS 8940 Desktop Motherboard wins for the stated Dell desktop board role. The board lists RJ-45, USB 3.1, USB 2.0, USB Type-C, M.2, SATA, PCIe, and headset connections, plus a maximum memory configuration of 128GB. That makes it the more relevant component when the central requirement is the motherboard itself and those listed connections or memory capacity matter.
Product notes
Intel Core i7-8700 SR3QS 3.20GHz 6 Core LGA 1151 Desktop CPU Processor
The Intel Core i7-8700 is the focused choice for someone sourcing a standalone processor rather than rebuilding around a new motherboard. It is identified as an Intel Core i7 8th Gen processor and carries the LGA 1151 socket designation, helping narrow the search to a particular desktop CPU format. The listed 1.5 MB L2 cache and 12 MB L3 cache add useful identifiers for matching the exact processor model. Its key limitation is straightforward: the sale is for the CPU only, and the condition is used. The i7-8700 therefore addresses a processor requirement, not a motherboard replacement or a board designed around the Dell XPS 8940.

The Dell XPS 8940 Desktop Motherboard is the sensible pick when replacing the board in the named Dell XPS 8940 setup. It is listed in new condition and identifies LGA1200 along with 10th- and 11th-generation Intel Core processor compatibility. Its connection list is especially useful for a board-focused purchase: it includes M.2, SATA, PCIe, several USB types, RJ-45, and a headset connection. The 128GB maximum memory configuration is another concrete planning detail for a memory-equipped desktop build. The limitation is its specific Dell XPS 8940 and processor-generation focus; it is not the indicated board choice for the i7-8700, which is listed as an 8th-generation LGA 1151 CPU.
Final choice by use case
Pick the Intel Core i7-8700 for a used standalone CPU purchase where an LGA 1151 processor is the target. Pick the Dell XPS 8940 Desktop Motherboard for a new motherboard centered on the Dell XPS 8940, especially when its listed port selection and 128GB memory configuration suit the planned system. These are complementary PC components in different roles, so the right choice follows the part that needs replacing.
