When shopping for cpus, motherboards & memory, the biggest mistake is comparing prices before confirming which component needs replacing. The G.SKILL Ripjaws S5 is desktop memory, while the Dell XPS 8940 item is a motherboard for a named desktop model. They solve entirely different problems.
Quick verdict
Choose the G.SKILL Ripjaws S5 when your upgrade calls for a DDR5 memory module for an Intel desktop. Choose the Dell XPS 8940 Desktop Motherboard when the job is replacing the main board in a Dell XPS 8940. At $379 and $161.58 respectively, the listed prices are far apart, but neither part can stand in for the other. Start with the component your system actually needs.
At a glance
| Detail | G.SKILL Ripjaws S5 | Dell XPS 8940 Desktop Motherboard |
|---|---|---|
| Listed price | USD 379.00 | USD 161.58 |
| Part category | DDR5 desktop memory | Desktop motherboard |
| Listed platform detail | Intel desktop memory with XMP 3.0 | Dell XPS 8940, Intel 10th and 11th Gen Core processors |
| Memory detail | 1 x 32GB module, DDR5-6000, CL32 | DDR4; maximum memory configuration of 128GB |
| Other listed detail | Unbuffered, non-ECC UDIMM | LGA1200 socket; USB, USB Type-C, M.2, SATA, PCIe, RJ-45 and headset ports |
Where each product wins
G.SKILL Ripjaws S5 wins for a memory-focused upgrade. Its listed DDR5-6000 speed and CL32 latency make it the relevant choice when the required purchase is a 32GB desktop memory module rather than a board. XMP 3.0 is also part of its named configuration.
Dell XPS 8940 Desktop Motherboard wins for a targeted system repair. The compatibility language specifically names the Dell XPS 8940 and Intel 10th- and 11th-generation Core processors with the H470 chipset. That makes it the more direct route when replacing the central board in that particular desktop.
Product notes
G.SKILL Ripjaws S5 32GB 1x32GB DDR5 6000 CL32 XMP 3.0 Intel Desktop Memory
This is the focused pick for someone adding or replacing a single 32GB memory module in a compatible Intel desktop memory setup. Beyond the speed and latency shown in the comparison, the Ripjaws S5 is described as an unbuffered, non-ECC UDIMM with a 33mm low-profile aluminum heat spreader. Those details make the module's format and physical profile clear for a shopper narrowing down desktop memory. Its concrete limitation is equally important: the listed configuration is one module, and it is memory rather than a motherboard. It addresses a RAM purchase, not a failed mainboard or a need for additional onboard ports.

This board makes the most sense when the replacement target is a Dell XPS 8940 itself. It is listed as new and includes a practical set of connections: USB 3.1, USB 2.0, USB Type-C, M.2, SATA, PCIe, RJ-45, and a headset port. That combination is useful context for a motherboard purchase because the board is the component carrying those connections, unlike a memory module. The limitation is its deliberately narrow compatibility wording: it is identified for Dell hardware and the XPS 8940 model. Shoppers pursuing a broader memory upgrade or a different desktop should not treat this as an alternative to the Ripjaws module.
Final choice by use case
Pick the G.SKILL Ripjaws S5 if your priority is a low-profile 33mm desktop memory module and that form factor suits your planned memory upgrade. Pick the Dell XPS 8940 Desktop Motherboard if you need an LGA1200 board for the named Dell desktop. The decision is straightforward: buy the G.SKILL for memory capacity and buy the Dell board for a model-specific motherboard replacement.
