PCPartPicker Price Trends are daily generated graphs showing historical price information for several categories of computer hardware. You might recognize them from the earlier analysis of rising RAM prices. Thousands of components are grouped into logical categories and combined with price data. The data is analyzed and presented as an intensity graph of price distributions with minimum, maximum, and average price trends.
With the new price trend graphs, you can easily keep track of computer hardware price patterns. Want to check whether overall RAM prices are rising or falling, or if a CPU will drop in price with the arrival a new architecture? No problem. Purchasing parts for your next build no longer needs to be guesswork.
And as a fun side-note, if you look close at some of the graphs, you can see some interesting artifacts in the data:
- Holiday sales are easy to spot. Makes it easy to recognize if a given component class goes on sale frequently, seasonally, or not at all.
- Here and here look like a retailer doing some price optimization (trying to find the best margin/volume tradeoff, I presume?) - I've seen Amazon do this stair step price reduction before - might even be able to auto-detect the pattern some day.
- Here is a retailer price error. Sometimes you'll see spikes in the opposite direction, which are often ridiculously inflated prices to reduce demand during stock shortages.
