HI everybody , i have asked the sellsman to place a core 2 duo processor of 1.8 ghz but instead he gave me 2.5 ghz dual core , did he looted me and can a dual core with higher clock speed can beat loe core 2 duo processor?

As and noted, "Core 2 Duo" is a branded Intel dual‑core family and "2.5 GHz dual‑core" is only a clock/spec — they are not the same kind of description. Short answer: you weren’t automatically looted. A higher GHz number can mean better throughput, but clock speed alone doesn’t tell the whole story. Microarchitecture (Core 2 vs older NetBurst/Pentium D vs AMD), L2 cache, FSB/memory subsystem and thermal headroom all change real‑world performance.

To be sure what you actually have, get the exact CPU model string and compare specs. On Windows you can run:

wmic cpu get name

or use a small utility such as CPU‑Z. On Linux try lscpu or cat /proc/cpuinfo | grep 'model name' -m 1. On macOS use sysctl -n machdep.cpu.brand_string. Copy that model text and check cache size, family (Core 2 vs Pentium D vs Athlon X2), and TDP before judging.

What to compare when deciding which is "better": architecture generation, per‑clock efficiency (IPC), L2/L3 cache per core, front‑side bus or memory controller, number of physical cores, and thermal/power limits. As and @johhny‑marshal implied, design matters: an older Pentium D with a higher clock can still lose to a lower‑clocked Core 2 Duo because of much lower IPC.

If the seller installed a compatible chip that’s equal or better, it’s a win. If it’s worse or not what was sold, keep the box/receipt, record the CPU model, show the specs, and request an exchange or refund. For a quick reality check run a simple benchmark or compare the model numbers on official manufacturer pages before escalating.

A core 2 duo is a dual core processor i do believe, so basically your going from a dual core 1.8Ghz cpu, to a 2.5Ghz cpu, is that what your asking?

core 2 duo is a line of dual core processors. depending what kind of dual core he installed, then yes... a 2.5 could be better than your core 2 duo @ 1.8 just make sure it wasn't a pentium D chip that he put in. the easiest way to see what CPU you have is, go to the start menu, and right click on 'computer'. click on properties.
a window will open showing you the processor you're running, the memory, the exact operating system you have, etc...

The 2.5 ghz dual core is a better chip than the 1.8 ghz Core 2. It is a better design with faster circuitry, not even considering the higher clock speed ghz speed.

Both belongs to the same class. Core 2Duo is just a step higher than Dual Core. You do not need to worry.
