AMD Radeon VII视频卡游戏性能初步研究：比Vega 64提高25%_我的网站

一 | 1月12日，AMD在今年的CES大会上正式发布了新的AMD Radeon VII图形卡。    Shares of Pfizer are in retreat on the first day of trading after the drug company said sales of its COVID-19 vaccine and its coronavirus treatment are weaker than it had expected and cut revenue projections by $9 billion for the year. Falling sales of both clipped sales in the second quarter, but Pfizer said in August that it expected a rebound in the second half of 2023. Shares of Pfizer slipped more than 1% before the opening bell Monday and Moderna, which is heavily reliant on the competing vaccine it makes, slid nearly 5%. Pfizer said Friday that global usage of Paxlovid is trending slightly above last year, but that it's still below expectations.The fall vaccination period just began and the New York City drugmaker said that it's too soon to get a handle on vaccination rates for the year.Full-year revenue for Paxlovid and Comirnaty is expected to be approximately $12.5 billion, short $9 billion of what it had expected. Pfizer is lowering its full-year revenue expectations for Paxlovid by approximately $7 billion. That number also accounts for delayed commercialization of the product, which was pushed to January 2024 from the company's previous expectation of commercialization in the second half of this year. Pfizer is also lowering its 2023 revenue expectations for Comirnaty by approximately $2 billion due to lower-than-expected vaccination rates.Pfizer Inc. now foresees 2023 revenue in a range of $58 billion to $61 billion, down from its prior forecast for $67 billion to $70 billion. It now projects full-year adjusted earnings between $1.45 and $1.65 per share due to lower-than-anticipated revenue for COVID-19-related products and inventory write-offs.That is short of the full-year revenue of $63.61 billion and earnings of $2.77 per share that Wall Street was expecting, and far short of the company's previous projections of per-share earning between $3.25 and $3.45. JPMorgan said the company's update solves an ongoing U.S. Paxlovid inventory debate and it anticipates the company's bigger-than-expected cuts to its sales projections will help put a floor under per-share earnings expectations for next year.。作为世界上第一款7nm图形卡，我相信每个人都对它的性能感到好奇，但AMD在其主旨演讲中只发布了少量的数据。但据外国媒体PC玩家称，AMD在官方新闻稿中披露了更多的测试数据。经过整理，国外媒体列出了25款游戏的测试数据，全部来自AMD的官方测试。AMD测试设备使用Intel Core i7-7700K处理器和16GB DDR4-3000内存，并将Radeon VII与Radeon RX Vega 64基准测试进行了比较。测试游戏画面设置为4K分辨率，最高质量，测试结果取三个平均值。

二 | 根据测试结果，Radeon VII的性能比Radeon RX Vega 64强28%左右。

三 | 根据测试数据，RADEON VII的性能在沉降物76中提高最多，达到68%。在《杀手2》中，两张图形卡之间的差距最小，只有8%。Radeon VII有60个cu s、3840个流处理器、1.8GHz核心频率、16GB hbm2内存和1TB/s内存带宽。AMD官员说，RADEONVII的“战场5”和“孤岛精神”框架在4K高质量上略高于RTX2080。

四 | 在“陌生旅”中，AMD Radeon VII领先于RTX 2080至14帧。AMD Radeon VII将于2月7日以699美元（4760元）的价格出售。
