'''GeForce 256'''— bu ''NVIDIA'' kominib, 1999-yil 11-oktabrda sotuvga chiqarilgan. GeForce 256 o‘zidan oldingi '''RIVA TNT2''' modeliga nisbatan sezilarli yaxshilanishlarga ega bo‘lib, unda doimiy piksel konveyerlar soni oshirilgan, geometriya hisoblashlari esa apparat darajasidagi transformatsiya va yoritish (T&L) dvigateliga yuklatilgan. Shuningdek, MPEG-2 videolari uchun apparat darajasida harakatni kompensatsiya qilish funksiyasi qo‘shilgan. Bu model 3D kompyuter o‘yinlari samaradorligini sezilarli darajada oshirib, Direct3D 7 standartini to‘liq qo‘llab-quvvatlagan birinchi 3D tezlpaniyasining “GeForce” mahsulot qatoridagi ilk grafik protsessoridir. U 1999-yil 31-avgustda e’lon qilatkich (accelerator) hisoblanadi.

'''GeForce 256''' - dunyodagi birinchi "GPU" yoki "grafik protsessor bloki" sifatida bozorga chiqarilgan. Nvidia bu atamani o‘sha paytda quyidagicha ta’riflagan: "integrallashgan o‘zgartirish, yoritish, uchburchak tuzish/kesish va tasvirlash mexanizmlariga ega bo‘lgan yagona chipli protsessor bo‘lib, u sekundiga kamida 10 million ko‘pburchakni qayta ishlash qobiliyatiga ega"<ref>{{cite web |title=nVidia unveils new computer graphics accelerator |url=https://money.cnn.com/1999/08/31/technology/nvidia/ |website=[[CNNfn]] |date=August 31, 1999 |qaralgan sana=2025-10-13 |arxivsana=2024-10-23 |arxivurl=https://web.archive.org/web/20241023155821/https://money.cnn.com/1999/08/31/technology/nvidia/ }}</ref><ref>{{Cite web |url=http://www.nvidia.com/object/gpu.html |title=Graphics Processing Unit (GPU) |website=www.nvidia.com |date=December 17, 2009 |access-date=March 24, 2016}}</ref>.

Uning nomidagi "256" "256-bitli QuadPipe Rendering Engine" dan kelib chiqqan bo‘lib, bu NV10 chipining to‘rtta 64-bitli piksel quvurlarini tavsiflovchi atamadir. Bir teksturali o‘yinlarda NV10 har bir siklda 4 ta piksel chiqarishi mumkin edi, ikki teksturali ssenariy esa buni har bir siklda 2 ta ko‘p teksturali piksel bilan cheklaydi, chunki chipda TNT2 kabi har bir quvurda faqat bitta TMU bor edi<ref name="auto">{{Cite web|url=https://www.anandtech.com/show/391|archive-url=https://web.archive.org/web/20120720100048/http://www.anandtech.com/show/391|url-status=dead|archive-date=July 20, 2012|title=NVIDIA GeForce 256 Part 1: To buy or not to buy|first=Anand Lal|last=Shimpi|website=www.anandtech.com}}</ref>.

''GPU(videokarta)ning'' o‘ziga o‘zgartirish va yoritish uskunalarining integratsiyasi GeForce 256 ni ushbu hisob-kitoblarni amalga oshirish uchun protsessorga tayanadigan eski 3D tezlatgichlardan (shuningdek, dasturiy ta’minotni o‘zgartirish va yoritish deb ham ataladi) ajratib turadi. 3D grafik yechimlar murakkabligining bunday qisqarishi bunday apparat vositalarining narxini yangi past darajaga olib keldi va uni kompyuter yordamida loyihalash (CAD) uchun mo‘ljallangan oldingi qimmat professional yo‘naltirilgan bo‘shliq bilan cheklanish o‘rniga arzon iste’molchi grafik kartalariga kirish imkonini berdi. NV10 ning T&L dvigateli, shuningdek, Nvidiaga birinchi marta CAD bozoriga Quadro deb nomlangan mahsulot bilan maxsus kartalar bilan kirishga imkon berdi. Quadro liniyasi GeForce kartalari bilan bir xil kremniy chiplaridan foydalanadi, lekin CAD ilovalarining o‘ziga xos talablariga moslashtirilgan turli xil haydovchi yordami va sertifikatlarga ega<ref>{{cite web |url=http://www.nvidia.com/page/workstation.html |title=Nvidia Workstation Products |publisher=Nvidia.com |access-date=October 2, 2007}}</ref>.

Faqat bitta GeForce 256 versiyasi mavjud edi, chunki keyingi GeForce mahsulotlari turli xil chip tezligiga ega bo‘ladi. Biroq, ikkita xotira konfiguratsiyasi mavjud bo‘lib, SDR versiyasi 1999-yil oktyabr oyida va DDR versiyasi 1999-yil dekabr oyi o‘rtalarida chiqarilgan - har biri turli xil SDRAM xotirasiga ega. SDR versiyasi Samsung Electronics kompaniyasining SDR SDRAM xotirasidan foydalanadi<ref>{{cite web |title=NVIDIA GeForce 256 SDR |url=https://videocardz.net/nvidia-geforce-256-sdr/ |website=VideoCardz.net |access-date=10 July 2019}}</ref><ref>{{cite web |title=K4S161622D Datasheet |url=http://www.datasheetcatalog.com/datasheets_pdf/K/4/S/1/K4S161622D.shtml |publisher=[[Samsung Electronics]] |access-date=10 July 2019 |arxivsana=2025-03-17 |arxivurl=https://web.archive.org/web/20250317115807/https://www.datasheetcatalog.com/datasheets_pdf/K/4/S/1/K4S161622D.shtml }}</ref> , keyingi DDR versiyasi esa [[Hyundai]] Electronics (hozirgi [https://www.skhynix.com/| SK Hynix]{{Oʻlikhavola|date=fevral 2026 |bot=InternetArchiveBot |fix-attempted=yes }}) kompaniyasining DDR SDRAM xotirasidan foydalanadi<ref>{{cite web |title=NVIDIA GeForce 256 DDR |url=https://videocardz.net/nvidia-geforce-256-ddr-64mb/ |website=VideoCardz.net |access-date=10 July 2019}}</ref><ref>{{cite web |title=HY5DV651622 Datasheet |url=http://www.ic72.com/pdf_file/h/169210.pdf |publisher=[[Hynix]] |access-date=10 July 2019}}</ref>.
