AMD Ryzen 5 vs. Ryzen 7: Which Ryzen CPU provides the most bang for your buck?

Price-performance index

How value-for-money is it?

AMD's Ryzen 5 processors are made more price competitive by virtue of the fact that they will work with AMD's more affordable B350 motherboards like the ASUS Prime B350-Plus pictured here.

It’s all well and good to talk about raw performance, but one metric that’s less clear is the price-to-performance ratio, which really just refers to how much bang you’re getting for your buck.

To suss out how worth your while each of the Ryzen chips really is, we’ve generated an aggregate performance composite index for each processor, comprising a single representative score from every benchmark we ran. The Ryzen processors do very well for tasks that properly leverage its heavily multi-threaded architecture, but are less impressive in gaming benchmarks, so this approach aims to take all these performance aspects into account.

We used the Intel Core i7-7700K as our baseline, which means it had an index score of 1.00. All the other scores were calculated relative to it, so a score of 1.15 for the Core i7-6950X means that it is 15 per cent quicker than the Core i7-7700K. Conversely, a score of 0.90 for the AMD Ryzen 7 1700 indicates overall performance that is 10 per cent slower.

That said, this comparison assumes that you’re more interested in overall performance as opposed to a single aspect like gaming or some other use case. If you’re interested in a particular usage model only, we’d refer you back to our individual benchmarks for a better gauge of performance.

In addition, we’ve included a separate price-performance index where we divided the performance composite index by the respective prices of each processor to get a rough indicator of how much performance you’re getting per dollar. Higher values indicate more performance per dollar spent, and we’ve arranged the graph below from the highest performance composite index to the lowest. We’ve also included a table with the local prices for each of our tested processors for easier reference.

  AMD Ryzen 7 1800X (3.60GHz, 16MB L3 cache) AMD Ryzen 7 1700X (3.40GHz, 16MB L3 cache) AMD Ryzen 7 1700 (3.0GHz, 16MB L3 cache) AMD Ryzen 5 1600X (3.60GHz, 16MB L3 cache) AMD Ryzen 5 1500X (3.50GHz, 8MB L3 cache) Intel Core i7-7700K (4.20GHz, 8MB L3 cache) Intel Core i7-6950X (3.0GHz, 25MB L3 cache)
Price S$818 S$599 S$499 S$359 S$289 S$545 S$2,562

Ultimately, the Ryzen 5 1600X and 1500X had the two highest price-performance indexes thanks to their relatively competitive performance and attractive prices. The Ryzen 5 1600X stands out in particular because of how close its performance is to the Ryzen 7 1800X, which is more than twice its price.

If multi-threaded performance is not a top priority, the Ryzen 5 1600X is looking to be a very attractive offering. It is also shaping up to be an excellent alternative to Intel’s mid-range processors, especially if you’re looking for a decent all-round performer.

As we mentioned earlier, we didn’t have the Core i7-7600K for testing, but that is a quad-core part with no hyperthreading that costs around S$380, more than even the 6-core/12-thread Ryzen 5 1600X. Having said that, if you're going to be dealing with heavily threaded workloads in addition to gaming, it is difficult to say no to the latter.

Finally, while we conducted our benchmarks with AMD's flagship X370 chipset, the Ryzen 5 chips are more likely to be used with cheaper B350-based boards that generally cost under S$200. This brings the overall cost of a potential Ryzen 5 system down, further bolstering the competitiveness of the series in terms of price.
