Core 2

Core i5 is family of mid-range performance 64-bit x86 processors designed by Intel for desktops and laptops. The Core i5 family was introduced by Intel in 2009, following the retirement of the Core 2 family. Core i5 microprocessors are positioned between the high-end performance Core i7 and the low-end performance Core i3.

Overview

Intel first announced the retirement of the Core 2 in mid-2009 and was introduced later the same year. Core i5 are mid-range performance processors with performance higher than those offered by the Core i3 processors but below those offered by Core i7. Core i5 processors usually have more cores than i3 (typically 4 vs 2 in i3), and offer more features (e.g. Turbo Boost Technology)

Members

Intel has traditionally been grouping Core i5 processors into generations based on the microarchitecture they are based on with 1st generation being based on Nehalem in 45 nm with the latest chips based on Kaby Lake manufactured using a 14 nm process.

1st Generation (Nehalem)

Main article: Nehalem Microarchitecture

1st Generation (Westmere)

Main article: Westmere Microarchitecture

Arrandale Core

The Arrandale-based i5 processors are dual-core processors. These processors had the FSB replaced with Direct Media Interface 1.0 and introduced AES instructions. These processors use Socket-G1. They all have the following features:

• Bus: DMI (2.5 GT/s) interface
• TDP: 18, 35 W
• ISA: Everything up to AES (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, and AES), and TXT.
• Tech: EIST, VT-x, VT-d, Hyper-threading, and TBT.

2nd Generation (Sandy Bridge)

Main article: Sandy Bridge Microarchitecture

Mobile

2nd Generation mobile Core i5 processors were based on Sandy Bridge, an entirely new microarchitecture that provided higher performance at higher power efficiency along with many other improvements and changes. Those new models also integrate a higher performance GPU onto the same die as the microprocessor as well as introduced a new SIMD AVX instruction set extension as well as a number of new technologies. It's also worth pointing out that the ulta-low voltage models are now 1 watt of TDP less than previous generation while having higher clock speed. All Core i5 has the following features in common:

• Chipset Bus: DMI 2.0 (5 GT/s)
• TDP: 17 W, 35 W
• ISA: Everything up to AVX (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, and AVX).
• Tech: SpeedStep (EIST), VT-x/EPT, Hyper-threading, FMA, Flex Memory, Identity Protection, and My WiFi
• Wireless: 4G WiMAX

3rd Generation (Ivy Bridge)

Main article: Ivy Bridge Microarchitecture

4th Generation (Haswell)

Main article: Haswell Microarchitecture

5th Generation (Broadwell)

Main article: Broadwell Microarchitecture

6th Generation (Skylake)

Main article: Skylake Microarchitecture

Desktop

See also: Skylake S

Intel released the desktop Skylake Mid-range processors in late 2015. All desktop Core i5 models utilize the LGA-1151 socket which is used for most of the Skylake desktop lineup.

laptop

See also: Skylake U and Skylake Y

Mobile Skylake-based Mid-range processors were introduced in late 2015. Mobile Core i5 uses FCLGA-1515/FCLGA-1356 sockets which incorporate the chipset as well as the microprocessor itself in the same package.

7th Generation (Kaby Lake)

Main article: Kaby Lake Microarchitecture

7th generation Core i5 processors, models which were introduced by Intel in early 2017, are manufactured on Intel's improved 14 nm process "14nm+" which allowed for higher clock speeds at similar voltage levels. As such most models enjoy a modest 100 to 300 MHz clock increase over their previous generation for the same price (Note that clock-for-clock there is no performance improvement over 6th generation Core i5). Overall very few minor features were introduced in the 7th Generation Core i5 models, including improved GPU support for 4K playback via native hardware acceleration. All models incorporate a 600-series integrated graphics processor which is largely identical to their 6th generation 500-series counterparts.

Desktop

Desktop 7th generation Core i5 processors were launched in January of 2017. While their clock-for-clock performance is identical to their 6th generation counterparts, they are clocked higher which allowed for a slight performance increase. All desktop models use Socket LGA-1151, are quad-core with no Hyper-Threading, and have the following common features:

• TDP: 35-65 W (with exception for the 7600K)
• ISA: Everything up to AVX2 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, FMA3, and AVX2)
• Tech: Turbo Boost 2.0, VT-x, VT-d, TSX, SpeedStep, Identity Protection, Secure Key, Software Guard (SGX), Memory Protection (MPX), OS Guard

Mobile

The 7th generation Mobile Core i5 processors which are based on the Kaby Lake microarchitecture were introduced in mid-2016 with later models introduced in early 2017. All mobile models use BGA-1356 socket for U-series models and BGA-1440 socket for H-series, are dual-core with Hyper-Threading, and have the following common features:

• TDP: 4.5-45 W
• ISA: Everything up to AVX2 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, FMA3, and AVX2)
• Tech: SpeedStep, Speed Shift, Turbo Boost 2.0, VT-x, VT-d/EPT, TSX, Flex Memory, Smart Response, My WiFi, Software Guard (SGX), Memory Protection (MPX), OS Guard, Secure Key

Embedded

Embedded 7th generation Core i5 processors were introduced in mid-2016 with later models introduced in early 2017. All mobile models have the following common features:

• TDP: 15-54 W
• ISA: Everything up to AVX2 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, FMA3, and AVX2)
• Tech: SpeedStep, Turbo Boost 2.0, vPro, VT-x, VT-d, TSX, Software Guard (SGX), Memory Protection (MPX), OS Guard

8th Generation

Main article: Coffee Lake Microarchitecture

8th Generation-core based on the Coffee Lake microarchitecture were introduced in early 2018. Those parts offer are manufactured on Intel's third generation 14 nm++ process which allowed for higher clock frequencies.

Desktop (Coffee Lake)

See also: Coffee Lake S

Coffee Lake-based Core i5s were introduced in late 2017 with a number of high-end SKUs. A larger number of SKUs were introduced in April 2018. Although they still use standard Socket LGA-1151, those parts are no longer backwards compatible with earlier 100/200-series chipsets and must be paired with an appropriate 300-series chipset. A significant configuration change has taken place with the introduction of Coffee Lake including bumping the core count for the Core i5s from 4 cores to 6 and appropriately increasing the L3 cache which has significantly increased the performance of those parts over the prior generation. Note that with the doubling of the core, Intel has dropped hyper-threading support from those models. All models have the following features in common:

• Hexa-core without Hyper-threading, 9 MiB L3$
• Mem: Up to 64 GiB of 2666 MT/s DDR4
• I/O: PCIe Gen 3.0 x16 lanes
• TDP: 95 W (HP), 65 W (SP), 35 W (LP)
• ISA: Everything up to AVX2 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, FMA3, and AVX2)
• Tech: Turbo Boost, VT-x, VT-d, EPT, SpeedStep (EIST), Software Guard (SGX), Secure Key, Memory Protection (MPX), OS Guard, and Identity Protection (IPT)
• GPU: UHD Graphics 630 @ 350 MHz with bursts of 1.05-1.15 GHz

Mobile (Kaby Lake Refresh)

In August 2017 Intel introduced 8th generation mobile Core i5 processors. Contrary to their namesake, those initial chips were still based on the same Kaby Lake microarchitecture as 7th generation. Those new microprocessors do bring some considerable performance increase in both single thread and more significantly in multi-threaded applications due to Intel doubling the number of cores from 2 to 4 while maintaining roughly the same price as previous generation. All mobile models still use soldered BGA-1356 socket and as with previous generation, those new mobile Core i5 chip also have Hyper-Threading enabled, providing 8 threads for all models.

• TDP: 15 W
• ISA: Everything up to AVX2 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, FMA3, and AVX2)
• Tech: SpeedStep, Speed Shift, Turbo Boost 2.0, VT-x, VT-d/EPT, TSX, Flex Memory, Smart Response, My WiFi, Software Guard (SGX), Memory Protection (MPX), OS Guard, Secure Key
