Help with numbers on CPU chip

[scoey1001]

Hi all,

I have a CPU chip and am trying to sell it on ebay. On the chip it says

Intel core i5

i5-8500

SR3XE 3.00 GHZ

V841B958 - e4

I've found a couple of similar ones for sale but none with this exact text. Can anyone explain what the 'SR3XE' and 'V841B958 - e4' means?

Thanks

Like this...



The SR3XE is part of the architecture of the chip, in this case the 'core stepping'.

https://www.cpu-world.com/Glossary/C/Core_stepping.html said:

Over course of its life, each microprocessor core could be refined or tweaked multiple times without changing or adding any major processor features. The purpose of the tweaks is to eliminate existing errata (errors in microprocessor logic), improve processor's stability or reliability, and/or enhance some electrical, thermal or other processor characteristics. Each new core revision with these changes are referred to as a core stepping, and the changes never affect CPU performance.

Knowing processor's exact stepping could be beneficial when you:

• need to match the processors for use in multi-processing system,
• get CPU that fixes certain errata,
• determine stepping-specific electrical and thermal characteristics, or
• to estimate your chances of successful processor overclocking.

The (e4) tells you which instruction set extensions it supports (i.e. SSE4 and AVX2).

intel.co.uk said:

Instruction Set Extensions are additional instructions which can increase performance when the same operations are performed on multiple data objects. These can include SSE (Streaming SIMD Extensions) and AVX (Advanced Vector Extensions).

The characters on the bottom, in front of the (e4) is the batch number, and will vary depending on when/where it was manufactured. This is not important unless there was a fault and you needed to know if your's was an affected unit.

Seen them sell over the last year for anything from £50-£100.
