Picking a processor against a memory module is not a conventional upgrade contest: the useful answer is to buy the PC part your build needs, not merely the lower-priced one. In CPUs, motherboards & memory, the Intel Core i7-8700 is a used desktop processor, while G.SKILL Ripjaws S5 is desktop memory. The decision is component role first and price second.
Quick verdict
Choose the Intel Core i7-8700 when the needed item is a six-core LGA 1151 processor and a used CPU-only purchase suits the build. Choose G.SKILL Ripjaws S5 when the needed item is DDR5 desktop memory with DDR5-6000 named in the model. The Intel is listed at USD 64, and the USD 315 price spread is substantial, but these are not like-for-like parts.
Listed-price and attribute comparison
| Choice | Listed price | Key listed details |
|---|---|---|
| Intel Core i7-8700 SR3QS | USD 64 | 3.20 GHz; six cores; LGA 1151 |
| G.SKILL Ripjaws S5 Memory | USD 379 | PC5-48000 (DDR5-6000) |
Where each product wins
- Intel Core i7-8700: The better fit when the shopping list specifically identifies an Intel Core i7 8th Gen processor with the SR3QS identifier. Its used condition and CPU-only scope also make it a targeted component purchase rather than a bundled collection of parts.
- G.SKILL Ripjaws S5: The relevant choice when selecting desktop memory with CL32 and XMP 3.0 in its name. Those model details make it easier to distinguish from a processor purchase, regardless of the price difference.
Product notes
Intel Core i7-8700 Processor
Intel Core i7-8700 is the focused pick for someone seeking that specific desktop processor rather than memory. The SR3QS identifier, 1.5 MB L2 cache, and 12 MB L3 cache provide concrete model details for matching an intended CPU purchase. Its practical limitation is condition and scope: it is marked used, and the purchase is for the CPU only. That makes sense for a shopper replacing or sourcing a processor, but it does not serve a memory-upgrade need. Choose the Intel chip when the Core i7-8700 designation is the requirement; leave it aside when the needed component is desktop memory.
G.SKILL Ripjaws S5 Memory
G.SKILL Ripjaws S5 is the focused choice when the wanted part is desktop memory rather than a processor. Its CL32 and XMP 3.0 naming gives shoppers two specific details to match, while the description identifies a 288-pin DIMM form factor and a low-profile 33 mm matte-black aluminum heat spreader. Those details help define the Ripjaws S5 selection without making it interchangeable with the Intel chip. Its limitation in this matchup is fundamental: it is desktop memory, while Intel Core i7-8700 is a processor. At USD 379, it also carries the higher listed price. Choose it for the named Ripjaws S5 memory role, not when the required part is a CPU.
Final choice by use case
Choose Intel Core i7-8700 for a purchase centered on a used, CPU-only processor. Choose G.SKILL Ripjaws S5 for a purchase centered on the named desktop-memory role. The correct winner is determined by whether the build needs a processor or memory module; the listed price difference is secondary to that basic component decision.
