Name: Intel BX80577T8300: Core 2 Duo T8300, 2.40 GHz, Socket P
Brand: Intel
SKU: BX80577T8300

Overview

The Intel Core 2 Duo T8300 is a mobile processor from Intel's Penryn family, released in early 2008 and manufactured on a 65nm process. Running at 2.40 GHz with two physical cores and a 3MB shared L2 cache, it was positioned as a mainstream performance option for laptops, sitting above budget Celeron and Pentium chips while remaining more affordable than the top-tier T9 series. The 800 MHz front-side bus provides adequate bandwidth for the architecture, and the 35W thermal design power was typical for full-performance mobile chips of the era.

As a Socket P processor, the T8300 is compatible with Intel's GM965, PM965, and related mobile chipsets, making it a drop-in upgrade for many laptops from that period. For users maintaining or reviving older machines, this chip can provide a noticeable improvement over lower-clocked or single-core processors from the same socket family. However, with only two cores, no hyper-threading, and no support for modern instruction sets, it is firmly a legacy component — best suited for basic productivity tasks, light media consumption, and running older operating systems that do not demand the resources of current hardware.

Pros & Cons

👍 Pros

Low 35W TDP provides reasonable power efficiency for its generation of mobile processors
3MB shared L2 cache improves multitasking responsiveness over lower-cache models
800 MHz front-side bus delivers solid bandwidth for the Core 2 Duo architecture
Drop-in Socket P compatibility makes it a straightforward upgrade for many older laptops

👎 Cons

Dual-core design with no hyper-threading severely limits modern multitasking capability
Legacy 65nm fabrication process is far less power-efficient than current architectures
800 MHz FSB is a bottleneck compared to later-generation processors
No support for modern instruction sets like AVX limits compatibility with newer software

Frequently Asked Questions

What socket type does the Intel Core 2 Duo T8300 use?

It uses Socket P (mPGA478MN), which is found in a wide range of mid-to-late 2000s laptops from manufacturers like Dell, HP, Lenovo, and others.

How does the 3MB L2 cache benefit this processor?

The 3MB shared L2 cache allows both cores to access frequently used data quickly, improving performance in multitasking scenarios and reducing memory latency compared to processors with smaller caches.

What is the thermal design power (TDP) of the T8300?

The Core 2 Duo T8300 has a 35W TDP, which was standard for full-performance mobile processors of its generation and balances performance with reasonable battery life.

Is this processor still suitable for modern use?

The T8300 is a legacy dual-core processor from 2008. It can handle basic tasks like web browsing and document editing on older operating systems, but it is not suitable for modern software demands or current operating systems.
