Toshiba Satellite L640D: AMD Vision

 

   สวัสดีครับ สำหรับวันนี้คือ Toshiba Satellite L640D มาในรูปแบบของ AMD Vision คงจะแปลกใจกันบ้างน่ะครับ เพราะเราคงไม่ค่อยได้เห็น Toshiba กับ AMD กันมานานพอสมควร แต่ในวันนี้เราจะได้เห็นเพลตฟอร์มของ AMD Vision มาในโตชิบา ซึ่งมีซีพียูเป็น AMD Turion™ II Dual-Core Mobile Processors ในรุ่นของ P520 และยังมีชิปกราฟฟิกของ ATI Mobility Radeon™ HD 5145 ซึ่งถือว่าเป็นอันดับต้นของ ATI Mobility Radeon™ HD 5000 Series ซึ่งตัวนี้เป็นรุ่นท็อปของการ์ดจอโน้ตบุ๊คของค่าย ATI ครับ และในส่วนที่เหลือของ  Toshiba Satellite L640D Series ก็จะเป็น
