Verdict

The Intel Core i3-9300 is a 9th Generation 'Coffee Lake' desktop processor featuring 4 cores and 4 threads with a base clock speed of 3.70 GHz and a max turbo frequency of 4.30 GHz. Built on a 14nm process, it includes 8 MB of Intel Smart Cache, supports up to 64 GB of dual-channel DDR4-2400 memory, and has a Thermal Design Power (TDP) of 62W. Main pros include its integrated Intel UHD Graphics 630, support for ECC memory which is rare for consumer i3 models, and a significant 2 MB cache increase over the i3-9100. Key cons include the lack of Hyper-Threading technology, an aging LGA 1151 socket compatibility, and limited multi-threaded performance compared to newer 10th Gen or higher alternatives.

What customers like about Intel Core i3 9300?

  • Capable of handling heavy gaming and 4K content when paired with a decent graphics card
  • Provides solid performance for multi-threaded applications and intensive development tasks like Eclipse
  • Supports ECC memory, making it a viable low-cost option for server or workstation use
  • Includes integrated graphics (UHD 630), which is a key advantage over 'F' series models
  • Features a 2MB L3 cache increase over the i3-9100, totaling 8MB
  • Maintains efficient power consumption with a 62W TDP and relatively low operating temperatures

What customers dislike about Intel Core i3 9300?

  • Limited multitasking and future-proofing due to having only 4 cores and 4 threads without Hyper-Threading
  • Struggles with some modern, highly demanding AAA titles like Assassin's Creed
  • Lacks overclocking potential due to a locked multiplier
  • Poor value proposition compared to AMD Ryzen alternatives which often offer more cores for the price
  • Significant price premium over the i3-9100F that may not be justified by the modest clock speed boost
  • The included stock heatsink and fan are reported by some users to be of low quality
