Hardware Comparisons
Head-to-head matchups of the most cross-shopped models on the used market, with live pricing data for both sides.
Dell PowerEdge R740 vs R750
The R740 and R750 are the two most-traded 2U Dell platforms on the secondary market. The 14th-generation R740 is the value workhorse; the 15th-generation R750 adds Ice Lake CPUs, PCIe 4.0, and DDR4-3200 at a meaningful price premium.
Compare pricing →Dell PowerEdge R640 vs R650
Dell's 1U dual-socket mainstays. The R640 (14th gen) and R650 (15th gen) mirror the R740/R750 relationship in a denser form factor favored for virtualization farms and colocation deployments.
Compare pricing →Dell PowerEdge R730 vs R740
A generation-gap comparison that comes down to budget floor versus support runway: the 13th-generation R730 sits near its price floor, while the 14th-generation R740 still has years of mainstream life left.
Compare pricing →HPE ProLiant DL380 Gen10 vs Dell PowerEdge R740
The classic cross-vendor matchup: the two dominant 2U dual-socket platforms of the Skylake/Cascade Lake era, functionally equivalent on paper and both abundant on the secondary market.
Compare pricing →HPE ProLiant DL380 Gen10 vs Gen11
Two generations apart and on opposite ends of the depreciation curve: the Gen10 has taken its steep first-owner loss, while the Gen11 brings DDR5, PCIe 5.0, and Sapphire Rapids CPUs at early-curve prices.
Compare pricing →Lenovo ThinkSystem SR650 vs Dell PowerEdge R740
The SR650 is Lenovo's answer to the R740 — same CPU generation, same 2U dual-socket formula, but a much smaller secondary-market footprint that cuts both ways on price.
Compare pricing →Cisco Catalyst 9300 vs 9500
Both are Catalyst 9000-series fixtures of the used enterprise networking market, but they serve different layers: the 9300 is the stackable access workhorse, the 9500 the fixed-form aggregation and core switch.
Compare pricing →Arista 7050X3 vs Cisco Nexus 9300-EX
The data center top-of-rack showdown: comparable 25/100G merchant-silicon switches divided mainly by operating system philosophy and licensing posture on the second-hand market.
Compare pricing →NVIDIA DGX A100 vs DGX H100
The two flagship AI systems of the modern era, now both appearing on the secondary market as hyperscalers refresh toward newer accelerators. Six figures separates them, and the calculus is about workload economics, not specs.
Compare pricing →NetApp AFF A400 vs Pure Storage FlashArray X50 R3
Two premier all-flash arrays with very different secondary-market personalities: NetApp's ONTAP ecosystem versus Pure's subscription-centric model, which heavily shapes what used units are actually worth.
