salam..

eii..pening betul bile buat design, laptop mula lembab macam siput baby..tu baru photoshop,illustrator..belum lagi nak pakai 3D max nak render bagai mau tumbuh janggut nih kang..adoilahh -.-" dah patut pertimbangkan sebuah PC.

sebagai seorang yang buta IT (bukan buta hati ok!), selame nih ade orang tolong set up semua, tapi sekarang harus lah berdikari..hukhukhuk

make so nye aku pun google lah kan, bace ape yang patut..so, sebelum kite cari spec yang paleng best mari kite amik tahu dulu ape kejadahkah CPU, Graphic Cards dan Hard Disk..pheww..kat sini aku pastekan terus sebagai info..

How To Build A Faster 3D CAD PC

CPU

The general rule of thumb when it comes to a CAD workstation is that, the CPU is king. The majority of CAD operations are CPU based so it’s a good idea to get the best one you can afford. The better the processor, the faster your rebuild and rendering times will be. The speed of a processor is referred to as its “clock speed” and is measured in GHz. The core count refers to how many cores per CPU. For instance, a 3.2GHz hex-core processor has 6 cores, each running at 3.2GHz.

More cores vs. higher speed?

Now, do you spend your hard earned cash on a CPU with a higher speed or more cores? That depends on what kind of work you will be doing, rendering or CAD design?

When rendering, you want as many cores as possible to get faster render times. A common misconception is that rendering is performed by the graphics card, when it is primarily CPU based. A even though rendering is primarily CPU based, some modern rendering programs can utilize higher end graphics cards for rendering. The graphics cards are essentially turned into an additional processor cores to aid the CPU in rendering.

Now, rendering is a multi-threaded operation, meaning it can utilize more than one processor core at a time. A quad core processor will render much faster than a dual core processor with a higher clock speed. The more cores you have, the faster you can render. There are motherboards that support multiple CPUs on a single board. For example, you could have two hex-core processors giving you a total of 12 processing cores.

On the other hand, modeling with 3D CAD software (such as SolidWorks) is primarily a single threaded operation. This means it will only use one CPU core at a time. So when speaking about CPU’s in regard to 3D modeling, the higher the clock speed, the better the performance. It may seem odd, but a dual core processor running at 3.5GHz will rebuild a complex part faster than a quad core running at 2.5GHz.

Many processor are also capable of running at much higher speeds than advertised by the manufacture. The process of manually increasing your CPU’s clock speed is called “Overclocking”. With overclocking you can increase your processors performance by changing timing and voltages of the processor to achieve a higher clock speed.

Overclocking often requires improved cooling for the processor such as a larger heat sink or liquid cooling, but can yield significantly improved performance. However, If not done properly overclocking can damage your hardware. So do your homework and proceed with caution! If you are nervous about overclocking, there are several companies that offer pre-overclocked computers with a warranty.

Graphics Card

After the processor, the graphics card (GPU) is considered the second most important piece of hardware. The graphics card handles the visual display of the model when you roll, pan or zoom. For 3D CAD applications you will need a professional, OpenGL graphics card.

There are are two main brands of workstation cards, the NVIDIA Quadro and ATI FirePro series. These graphics cards range in price from $100 all the way up to $2,000+. These OpenGL cards are considerably more expensive than their DirectX based “gaming” counterparts, but are necessary for most 3D CAD applications.

The easiest way to think about the difference between OpenGL and DirectX is an OpenGL card calculates higher detail models at relatively low frame rates, while a DirectX card calculates lower detail models at high, sustained frame rates.

When choosing a graphics card you want to keep in mind the type of work you will be doing. If you work on very large assemblies with lots of models you will want a graphics card with more memory. If the graphics card does not have enough memory, the frame rate will lag or stutter when moving the model. However, most users won’t need more than 256MB memory and can get away with a cheaper card.

It is possible to use DirectX cards for 3D CAD, however some features may not function properly (such as SolidWorks RealView) and you may experience slow frame rates as well as graphical glitches.

Hard Drives

Although not as important as a CPU or graphics card for CAD work, the hard drive can have a significant impact on overall performance. Hard drive technology has come a long way in the past few years. With the rise of the Solid State Drive (SSD) transfer speeds have increased dramatically.

The fastest traditional disk drives have a transfer speed of around 100MB/s, while modern SSDs range from 120MB/s to 750MB/s (and getting faster!) The faster transfer rate of the SSD will let you save and open models faster, make programs start faster, and decrease your computers boot time.

The downside of the SSD is its cost. Although the price has come down significantly in the past few years, an SSD is still considerably more expensive per GB. That being said, in my opinion an SSD is worth every penny. The massive performance increase over disk drives is very noticeable. Because of the cost, it is a good idea to use a small SSD as the main drive for the operating system and programs, and a high capacity disk drive as a media/storage/backup drive drive.

kay dah paham?

aku yang tak paham HAHAHA..kalau tak paham bace jom bace plak yang studio mate aku nih bagi, dalam bahase melayu senang sikit nak paham hihi :

Tips : Build good PC for 3D Works

mungkin ade yg tgh merancang utk buat PC yg ok especially for ID ble bukak sem baru nanti.. ini dia tips2 yg sy boleh kongsi.

Untuk buat satu sistem yg optimum, price-wise, senaraikan dulu:

1. Bajet yg ade
2. Guna PC untuk apa
3. Software yg anda akan guna
4. "kerajinan"dan tahap kemahiran anda utk jaga dan ubahsuai PC

1. Bajet 

faktor paling utama utk buat sistem yang ok. pada pndangan sy, bajet minimum utk buat PC yg bagus dalam RM2000-RM2500
Anda bole dpt spec yg sederhana dgn harga ni jika anda tidak beli PC branded spt DELL, HP, ACER dan lain2. jika anda beli yg branded, hrga akan tinggi sedikit.

2. Kegunaan PC. 

ini penting supaya tidak berlaku pembaziran. Jika anda bukan kaki games, anda x perlu beli graphic card (GPU) yg mahal. Games akan fokus pada graphic processing dan utk kerja spt AutoCAD, 3Ds Max, Photoshop, lebih kpd CPU
(processor, AMD, Intel). Jadi utk kegunaan kerja2 dlm ID, sy sarankan lebih fokus pada CPU. Graphic card Nvidia geforce atau ATI Radeon dgn memory 1gb sudah lebih dr cukup. Sy sndiri hanya guna NVIDIA Geforce GT220 512 MB.

Utk CPU, jika anda memilih performance, seeloknya pilih Intel i5. Jika mahu yg murah dgn performance sederhana anda boleh pilih AMD Phenom II x4,x6 atau AMD FX x4, x6 bergantung kpd bajet anda..Kalau mampu, anda boleh pilih i7 atau x8.
Beza Intel dgn AMD, Intel lebih tahan haba, lebih laju dan semestinya lebih mahal. AMD lebih murah tetapi mudah utk di overclock, tetapi perlu lebih penjagaan kerana kurang tahan haba. Kelebihan AMD, ia senang di upgrade krn socket boleh support newer and older model tp intel umumnya mempunyai socket berbeza utk setiap family.biasanya geeks akn memilih AMD..

3. Software yang akan diguna.

biasanya, utk kerja2 berat, windows 64 (x64) lebih sesuai digunakan. kelebihan sistem x64, ia membenarkan anda mengguna memory (RAM) lebih dari 3.5GB dan ke atas. Sistem x32 maksimum penggunaan memory tidak lebih dari 3.5 gb walaupun anda telah pasang RAM sebanyak 8GB. Walaubagaimanapun, ia juga bergantung kpd applications. 32-bit based application umumnya hanya akan guna maksimum 2GB RAM utk operasi walaupun dipasang di x64 Windows. Terdapat software utk hack 32-bit application supaya mampu support lebih 4gb RAM, sy akn share jika ad pemintaan.
Jadi jika anda berhasrat membeli original copy utk windows and software, anda perlu teliti tentang perkara ini.

3D Rendering
terdapat 2 jenis processing utk render 3d:
a.CPU based processing
b.GPU based processing

CPU based processing andalah standard yang sering diguna. Contoh sistem yg guna CPU processing ialah V-Ray, MentalRay, Brazil, finalRender POV-Ray dan lain2. Sistem ini mengguna 100% keupayaan CPU utk process image. Semakin laju CPU, semakin cepat proses untuk render, walaupun GPU anda tidak laju.

GPU pula menggunakan keupayaan graphic card samada 100% GPU atau gabungan CPU dan GPU processing. Dikenali juga sebagai Real-Time rendering. Sistem ini menyamai graphic engine dalam game. Cara ini lebih cepat, tetapi memandangkan ia masih baru, kualiti yg dihasilkan tidak secantik CPU processing.. tetapi teknik ini sesuai untuk render 3D animation. Contoh sistem GPU rendering ialah iRay, Quicksilver, Nitrous, Vray RT. GPU rendering hanya baru diperkenal utk 3ds Max 2011 dan ke atas. Software seperti Lumion 3d yg sering diguna oleh student architecture menggunakan sepenuhnya graphic engine and real-time rendering.

Jadi, terpulang kpd anda, jika mahu guna GPU, anda boleh guna graphic card lebih tinggi. ttp jika anda guna CPU, tidak perlu guna graphic card high-end.

4. jika anda jenis pengodam, 

suka modify PC, anda ada byk kelebihan. menggunakan sistem AMD memudahkan anda utk overclock CPU dan juga GPU.
OVERCLOCK ialah mengubah kelajuan CPU atau GPU melebihi kelajuan standard yg ditetapkan. cthnya AMD FX 4100 berkelajuan 3.6 GHz, di overclock kpd 4.1Ghz. jika silap langkah, ia menjejaskan stability. cara ini juga menjejaskan warranty produk tersebut. jadi jika anda mahir, anda mungkin tidak perlu beli model yg mahal untuk performance yg tinggi.
Walaubagaimanapun, untuk overclock, anda perlukan penjagaan yang rapi terutamanya haba yg dihasilkan oleh cpu, jika berlebihan akan merosakkan sistem.begitu juga dgn kawalan voltage sistem, jika kurang, x mampu utk naikkan clock, jika berlebihan, meletop.. boom!. 

Jadi anda perlu sistem penyejuk yg baik samada Air coolling ataupun Liquid Cooling jika mampu. Jadi pemilihan casing yg sesuai penting utk tujuan ini.. kalau rse creative, buat case sendiri.. :)). Jgn cuba jika anda tiada kemahiran tentang ni.. UTK PRO SAHAJA.. HAHA :P

Ini tips yg saya boleh kongsi, berdasarkan pengalaman dan kajian sy. jikalau anda berkemampuan utk branded PC, anda mungkin x perlu penjelasan pnjg sebegini. begitu juga dgn laptop ataupun Apple. Ini berguna jika anda mahu menjimatkan kos tp dgn performance yg optimum..
(credit to omar, thnx omar! -omar nih mmg sgt power dgn komputer & 3D! semua benda custom made, kalau keyboard n mouse boleh buat sendiri pun die dah buat sendiri, salute!)


so skang dah tau kan spec nyer..jom pegi cari budget plak..pheww..(jahanam duet shopping aku setaun -.-" ape-ape lah yang penting keje jalan nak buat presentation pun baru lah gempak an..ann..)
