Perbedaan Core Duo dan Core 2 Duo [Intel]

Perbedaan Core Duo dan Core 2 Duo [Intel]
« on: November 24, 2007, 12:35:57 PM »

Intel mengklasifikasikan prosesor untuk PC Desktop dan Notebook dalam tiga keluarga prosesor yaitu :
1. Intel Celeron
2. Intel Pentium
3. Intel Core

Core duo berarti dua inti prosesor dalam satu chip (rumah/kemasan prosesor) dan termasuk dalam keluarga prosesor Intel Core.

Pada PC Desktop dikenal dengan dual core dan ini terkadang disalahtafsirkan oleh pedagang komputer sebagai prosesor Core Duo.

Core Duo adalah teknologi terbaru (keluarga prosesor Intel Core) yang hendak diterapkan Intel bagi Notebook. Seiring perkembangan diadakan perbaikan/pengembangan yang menghasilkan Core 2 Duo. Sepertinya Intel berkeputusan untuk juga menggunakan teknologi Core 2 Duo pada PC Desktop. Sehingga PC Desktop saat ini bisa mengadopsi teknologi Core 2 Duo tanpa perlu mengalami fase Core Duo.

Kesimpulan umum
- Core Duo dan Core 2 Duo memiliki dua inti prosesor !
- Core Duo diciptakan untuk Notebook, seiring perkembangan diciptakan teknologi Core 2 Duo yang mana selain bisa digunakan untuk notebook juga bisa digunakan oleh PC Desktop.
- Tidak ada processor Core Duo untuk PC Desktop yang ada yaitu langsung Core 2 Duo, sebelumnya dua inti prosesor juga sudah pernah diterapkan pada PC Desktop yaitu pada keluarga prosesor Pentium diantaranya adalah Pentium Dual-Core dan Pentium D namun microarchitecture antara keluarga prosesor Intel Pentium dan keluarga prosesor Intel Core tersebut sangat jauh berbeda termasuk ukuran transistornya. Perbedaan tersebut mempengaruhi kinerja, tingkat kebutuhan energi/daya (wattage), dan panas yang dihasilkan. Pada Core 2 Duo kebutuhan energi dan panas yang dihasilkan jauh lebih kecil dibadingkan pada keluarga prosesor Intel Pentium yang berintikan dua prosesor.

Teknologi & Fungsi
Intel® Virtualization Technology (Intel® VT±)
Allows one hardware platform to function as multiple “virtual” platforms. For businesses, Intel VT Technology offers improved manageability, limiting downtime and maintaining worker productivity by isolating computing activities into separate partitions.
Intel® Trusted Execution Technology (Intel® TXT±)
Provides hardware-based mechanisms to help protect against software-based attacks and help protect the confidentiality and integrity of data stored or created on the system. It does this by enabling a trusted environment where applications can run within their own space, protected from all other software on the system.
Enhanced Intel Speedstep® Technology
Enhanced Intel Speedstep Technology allows the system to dynamically adjust processor voltage and core frequency, which results in decreased power consumption, which results in decreased heat production, which in turn allows improved acoustics because fans do not need to spin as quickly. Systems supporting Enhanced Intel Speedstep Technology require a compatible BIOS, a compatible operating system, and a compatible Intel processor.
Execute Disable Bit°
Intel's Execute Disable Bit° functionality can help prevent certain classes of malicious buffer overflow attacks when combined with a supporting operating system. Execute Disable Bit allows the processor to classify areas in memory by where application code can execute and where it cannot. When a malicious worm attempts to insert code in the buffer, the processor disables code execution, preventing damage and worm propagation. Replacing older computers with Execute Disable Bit-enabled systems can halt worm attacks, reducing the need for virus-related repairs. In addition, Execute Disable Bit may eliminate the need for software patches aimed at buffer overflow attacks. By combining Execute Disable Bit with anti-virus, firewall, spyware removal, e-mail filtering software, and other network security measures, IT managers can free IT resources for other initiatives. Enabling Execute Disable Bit functionality requires a PC with a processor with Execute Disable Bit capability and a supporting operating system.

Core 2 Duo
- Architecture: 65nm
- Memiliki beberapa fitur tambahan yang tidak terdapat pada Core Duo seperti :

* Intel® Wide Dynamic Execution: Enabling delivery of more instructions per clock cycle to improve execution time and energy efficiency.
* Intel® Smart Memory Access: Improving system performance by optimizing the use of the available data bandwidth.
* Intel® 64: Enables the processor to access larger amounts of memory. With appropriate 64-bit supporting hardware
and software, platforms based on an Intel processor supporting Intel 64 architecture can allow the use of
extended virtual and physical memory.

Berikut adalah pertanyaan yang saya ajukan ke staf teknis Intel Corporation:
I see that you group the processors into 3 families, those are, Intel Core, Intel Pentium, and Intel Celeron. I believe there's a reason that you classify the processors into those 3 families, so what makes one belong to a family, what's the difference between them? Is it the processor's architecture, amount of core processor within and its relative, or else?
As you can see, there is no particular reason for the classification of the processors in terms of categorization; however, a processor must have certain characteristics to belong to a family. Some of the features that we take into considerations when classifying processor are speed, FSB, Dual Core(TM) Technology, Hyper-Threading Technology, Intel(R) Extended Memory 64 Technology, Cache memory, Intel(R) Virtualization Technology, Enhance Intel(R) SpeedStep technology, among many others. Bear in mind that not all processor would share the same features. There is also an engineering background to take into account that is related to the architecture used when building up the processor.
As you might have noticed, the classification of the processors is mostly related to physical and electronic characteristics. This is why, for example, we do not compare and/or comment about processors in terms of performance, since it would mostly depend on the motherboard and software loaded on the system and not on the processor itself.
Catatan: Pertanyaan yang saya ajukan via email dijawab dalam waktu kurang dari 17 jam walapun saya bukan merupakan pelanggan, bandingkan dengan kebanyakan perusahaan besar di Indonesia (perbankan & Cellular provider/GSM dengan kapitalisasi triliunan rupiah) yang terkadang lewat 2 hari email dari pelanggan baru dibaca/ditindaklanjuti sekalipun itu adalah keluhan pelanggan, ironisnya satu dua kali tiada balasan sama sekali!!
