Product overview of the Intel SLB46

The SLB46 Intel Core 2 Duo T9400 2.53GHz Processor is a mobile processor designed for laptops and other mobile computing devices. It was introduced in 2008 and is part of the Intel Core 2 Duo family of processors. The SLB46 is built on a 45nm process and has a thermal design power (TDP) of 35 watts. This processor is compatible with the Socket-PGA478 interface and has a front-side bus (FSB) speed of 1066MHz.


The SLB46 Intel Core 2 Duo T9400 2.53GHz Processor is based on the Penryn microarchitecture, which was introduced by Intel in 2007. The Penryn architecture is a successor to the Merom architecture and is based on a 45nm manufacturing process. This architecture features several improvements over the Merom architecture, including a larger L2 cache, faster clock speeds, and improved power efficiency.

Cache Size

The SLB46 Intel Core 2 Duo T9400 2.53GHz Processor has a 6MB L2 cache, which is larger than the 4MB L2 cache found in the previous generation of Intel Core 2 Duo processors. The L2 cache is a type of memory that is located on the processor and is used to store frequently accessed data. The larger the L2 cache, the faster the processor can access data, which can result in improved performance for certain tasks, such as video editing, 3D rendering, and gaming.

FSB Speed

The SLB46 Intel Core 2 Duo T9400 2.53GHz Processor has a front-side bus (FSB) speed of 1066MHz. The FSB is the interface between the processor and the motherboard and is used to transfer data between the two components. A faster FSB speed can result in improved performance, particularly for memory-intensive tasks such as multitasking, video editing, and gaming.

Power Consumption

The SLB46 Intel Core 2 Duo T9400 2.53GHz Processor has a thermal design power (TDP) of 35 watts. TDP is a measure of the amount of heat that a processor generates and is used to determine the cooling requirements for a system. A lower TDP can result in improved power efficiency and longer battery life for mobile computing devices.


The SLB46 Intel Core 2 Duo T9400 2.53GHz Processor is compatible with the Socket-PGA478 interface, which is used by many laptop and mobile computing devices. This socket interface allows for easy installation and replacement of the processor. The SLB46 is also compatible with a wide range of chipsets, including the Intel 945GM, Intel GM965, and Intel PM965 chipsets.

About New Bulk Pack Products

New Bulk Pack products come with clamshell boxes and do not have any manufacturer warranty. Many times manufacturers disassemble whole units to use parts or pulled from a new system. Typically, this product doesn't come with software or instructions unless indicated and no Manufacturer’s genuine warranty. You can take note these are not brand new products.

The Intel Core 2 Duo is the successor of the core duo. This processor was introduced in 2007 and is based on the Pentium M microarchitecture. The processor has a good performance, with some series able to clock at 3.33GHz. The cache memory is either 2MB or 4MB, depending on the model that you choose. For example, Intel Core 2 duo E6700 has 4MB L2 cache while E4400 has 2MB L2 cache memory.

High Performance and Energy-Efficient

Intel Core 2 Duo are desktop and laptop processors designed to give you high-performance with insane system responsiveness. They are 40% faster and 40% more energy-efficient than their predecessors and use less voltage for their operations, leading to lower power consumption. That makes it possible for your computer to last many hours on backup power or an inbuilt battery.

The Core 2 Duo is designed from the ground up to consume as little energy as possible. As a result, you don't need your computer fan to be running at maximum speed. That has led to the construction of sleek and quieter computers and laptops. It will also help you save on the electricity bills.

Intel Core 2 Duo Processors for Multitasking

It is not accidental to have more than one application running on your computer. In many cases, you can have background music while editing a document or media file. These processors are designed to offer you that capability. You don't have to be worried about the applications that were left running in the background. That would be an issue of great concern with the previous versions of Intel processors, but not with the Core 2 Duo.

The Intel Smart Memory Access

Reducing the data bandwidth is a way of ensuring that the available memory is effectively used. That is what the Core 2 Duo brings to the table. Its high-performance is made possible with the Intel Smart Memory Access technology. The same goes for cache memory management. Intel Core 2 Duo processor has more efficient cache memory subsystems, optimized for a multi-core CPU.

Intelligent Power Management Capability

We have mentioned that this processor is very energy efficient. That is inherent in the design because of the dynamic execution. More instruction sets can be fetched in just a single clock cycle, thereby improving the execution time. Less execution time results in less power usage. The overall design of this processing unit is to deliver energy-efficient performance.
